Symposium 1 – 0900-1200
IFCC Expert Insights on Quality improvement in Laboratory Medicine and Patients’ Safety

When patients’ safety depends on our capacity to record and report laboratory errors

Pieter Vermeersch, Belgium, member of the WG-LEPS and Chair of the Post-Analytical WG of the EFLM

The pre-analytical phase is the most important source of errors in the total testing cycle. Pre-analytical errors can render the results worthless and can have a detrimental effect on a patient’s health.

Although the pre-analytical phase is mostly performed outside of the laboratory environment, the clinical laboratory has a major responsibility in decreasing vulnerability to these errors. ISO15189:2022 requires that laboratories check the suitability of samples upon reception and indicate any pre-analytical non-conformities on the lab report. Pre-analytical non-conformities include problems regarding identification, sample quality (e.g. stability) and interference due to hemolysis, icteria, and lipemia (HIL). Systematic error monitoring and registration and monitoring of pre-analytical quality indicators is important for continuous quality improvement.

Laboratory medicine professionals should carefully consider how to report the impact of pre-analytical non-conformities on laboratory test results. Hemolysis and lipemia can for example be an artefact of sample collection, but can also reflect a clinically important pathologic state. Not reporting any result in case of hemolysis or lipemia can result in a missed diagnosis of a potentially life-threatening severe hyperkalemia or hypertriglyceridemia. As not all parameters are equally susceptible to interference by hemolysis, icteria and lipemia, it is recommended to indicate on the laboratory on a test by test basis which results are impacted by the non-conformity.

One of the challenges for the coming years is standardized coding of non-conformities and their impact on laboratory test results as more and more data are exchanged electronically both nationally and internationally. The transmission of test results between countries for routine patient care using a different national databases and different languages as envisioned by the European health data space poses a particular challenge. Without standardized coding essential information about pre-analytical non-conformities and their impact on test results could be lost in translation. An effort is currently underway to develop terminology in LOINC and SNOWMED-CT.

Learning Objectives – at the end of this presentation participants will be able to:

  1. Discuss the frequency and impact of errors in the pre-analytical phase.
  2. Convince laboratory professionals to systematically record sample non-conformities and report the impact on laboratory test results.
  3. Explain the need to code sample non-conformities and include this coded information in the electronic exchange of laboratory test results.

Still existing challenges will be discussed, such as the integration of indicators data with laboratory information systems and the continuing education of laboratory professionals in indicator management, as well as potential actions to overcome them. Some relevant differentials of the Brazilian program will be presented, highlighting an expanded scope of indicators, which includes strategic dimensions to contribute to the sustainability of laboratories, as well as initiatives to deepen indicators within specific disciplines, such as indicators in laboratory microbiology.

Learning Objectives – at the end of this presentation participants will be able to:

  1. Outline the Brazilian clinical laboratories and the health system.
  2. Discuss existing regulatory requirements (which include structuring a quality system).
  3. Discuss clinical laboratories’ adherence to accreditation and laboratory indicators programs, as well as the results obtained.

Implementing the WG-LEPS guidelines to the national level, the Indian experience

Sohini Sengupta, India, member of the WG-LEPS, Member of the IFCC POCT Committee

The Indian medical diagnostics segment has been able to provide access to modern diagnostics facilities even to people living in remote areas. The total number of clinical laboratories in India is estimated to be over hundred thousand, which includes hospital and stand-alone labs, national and regional chains. However, this sector is fragmented and non-standardized, with only 1985 laboratories presently accredited by the NABL, the national accreditation body for medical laboratories. The use of quality indicators for evaluating the different phases of laboratory testing was therefore initially very limited. However, the number of accredited labs is increasing rapidly and the number of those with NABL accreditation has increased at a CAGR of around 20% between 2012–2017. In the next 5 years, many more laboratories in the country are expected to opt for accreditation. Test quality has improved over the years with more automation and more sophisticated tests being performed.

Consequently, awareness about quality indicators as a measurement of performance metrics is gradually increasing. The process of monitoring quality indicators is, however, still planned by individual laboratories, and while all strive to cover the total testing process, there is still enormous variation in the indicators they use. The periodic review of indicators to ensure their continued appropriateness is also limited.

Results from review of quality indicator data shows that in India too, 70% of errors tend to occur in the pre-analytical phase, important causes being improper registration, and temperature deviation during transport (particularly in the hub & spoke model), resulting in increased rejection of samples. Errors in the analytical phase are minimal, while the principal concern in the post-analytical phase is transcription errors, and compliance with turnaround times. Still, there remains a significant gap in capturing real-world data, due to differences in the choice of indicators or methodologies of data collection used. Efforts are being made to involve the national society and accreditation bodies in disseminating the WG-LEPS guidelines and standardize the use of quality indicators and process of data capture.

Learning Objectives – at the end of this presentation participants will be able to:

  1. Discuss standardization of the use of Quality indicators in India according to the guidelines of the IFCC WG-LEPS.
  2. Discuss monitoring its performance and review its continued appropriateness in the Indian context.
  3. Promote involvement of the National Society and accreditation bodies to increase compliance of clinical laboratories to the WG-LEPS guidelines.

R2: Plasma pTau 217 as a robust biomarker for the diagnosis and differential diagnosis of Alzheimer’s Disease


Hans Frykman, University of British Columbia-BC Neuroimmunology Lab, Vancouver; US Neurocode Labs

Dementia is the most common type of neurodegenerative disease, with Alzheimer’s Disease (AD) constituting about seventy percent of these cases. It is projected that the number of AD cases in Canada will reach 674,000 people by 2031, nearly doubling from the baseline of 340,000 people living with dementia in the country in 2011. AD is a complex condition with definite pathological findings and various clinical presentations. Its neuropathologic features are defined by amyloid-beta (Aβ) plaques and neurofibrillary tangles with aggregated tau proteins, causing neuroinflammation, reactive astrogliosis, and gradual synapse and neuronal loss with transmitter deficiencies, leading to slow and progressive cognitive impairment. Although an amnestic syndrome with insidious onset and gradual progression is the typical clinical phenotype of AD, an important proportion of cases with AD pathology present with non-amnestic cognitive disorders. Additionally, AD neuropathological cascades start years before the apparent beginning of the clinical symptoms of the disease and spread in a consistent pattern with subsequent neuroanatomical and neurophysiological changes. Therefore, clinical findings of AD are in a continuum but remain heterogeneous from cognitively unimpaired through mild cognitive impairment (MCI) to severe dementia. MCI is a prodromal stage of AD, and patients with amnestic MCI progress to probable AD at a rate of ∼10–15% per year, while 11%–33% of them develop it within the first 2 years. Moreover, AD pathology can frequently co-occur with other neurodegenerative and vascular diseases, and accurate timely differential diagnosis is critical for appropriate care and precise treatment strategies.

Understanding the role of biomarkers in the early diagnosis of AD appears imperative. Pathophysiologic biomarkers, including amyloid PET, and fluid biomarkers such as CSF concentrations of Aβ, tau proteins, and NfL along with plasma concentrations of Aβ, tau, and NfL, helping clinicians recognize and differentiate AD from other types of dementia and neurodegenerative diseases. The CSF Aβ42/Aβ40 ratio measurement is a robust biomarker in detecting cerebral Aβ pathology and AD diagnosis. A noticeable feature of the Aβ42/Aβ40 ratio is that their levels are altered in the preclinical stages of AD. They can identify Aβ pathology with high accuracy in both individuals with unimpaired cognition and patients with MCI. Plasma pTau217 and pTau181 can differentiate AD from other forms of dementia and tauopathies; however, the diagnostic performance of pTau217 is similar to that of both CSF biomarkers, and tau-PET imaging. In several clinical and analytical validations, we showed that plasma pTau217 (AUC 0.92 to 0.93) exhibited enhanced clinical performance compared to pTau181 (AUC 0.81) for diagnosing AD. Notably, plasma pTau217 begins to change earlier than other pTau variants, serving as a useful predictive tool for diagnosing AD in its preclinical stages.

In this round table, we discuss the markers of biological diagnosis of AD based on ATN biological assessment of AD (Aβ, Tau and Neurodegeneration markers). We also explain the different laboratory techniques for detection of these biomarkers and their accuracy based on our several clinical and analytical validation studies.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Recognize new technologies and protocols for the detection of AD biofluid biomarkers.
  2. Discuss accuracy of various biofluid biomarkers in diagnosis and differential diagnosis of AD.
  3. Determine how plasma pTau as robust biomarker could act as paradigm shift in the prevention and management of AD.


R4: Changing landscape of pharmacogenetic testing


Lei Fu, Sunnybrook Health Sciences Centre and University of Toronto, Toronto

Pharmacogenetic (PGx) testing is a fast-evolving and essential tool for personalizing drug therapy based on a patient’s genetic makeup. Several single-gene-drug pair PGx tests have become part of standard care to optimize drug therapy, prevent adverse drug reactions, and improve patient safety. To meet the increasing clinical demand, pre-emptive multigene panel testing would be an ideal strategy to have actionable PGx results ready before prescribing any target drugs. Advancement of next-generation sequencing (NGS) technologies provides opportunities for large-scale PGx studies and pre-emptive PGx testing to cover wide range of variant alleles present in diverse populations. In this roundtable session, we will review the common PGx tests implemented in clinical settings, use cases to demonstrate the effectiveness as well as limitations of current testing methods, and discuss different technologies and future development in PGx testing.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Describe the gene-drug pairs commonly implemented in PGx testing.
  2. Discuss the advantages and limitations of different technologies and testing strategies.
  3. Explore the future development and NGS-based PGx testing.


R5: Comprehensive Serological Evaluation of Autoimmune Encephalitis and Paraneoplastic Syndrome: how to choose the right laboratory test/panel and when to send CSF and/or serum


Pankaj Kumar, University of British Columbia BC Neuroimmunology Lab, Vancouver

Neural autoantibodies (NAbs) in various neurological autoimmune diseases are classified based on the location of their target antigens. One group of NAbs targets cell-surface antigens, including ion channels, water channels, and neurotransmitter receptors. These are linked to conditions such as Autoimmune Encephalitis (AE). The second group of NAbs targets intracellular antigens and is frequently associated with cancer, known as classic paraneoplastic neurological syndrome (PNS). The conventional methods to detect AE/PNS Ab, includes ELISA, immunoblotting, cell-based (CBA) and tissue-based assays (TBA). However, the latest PNS-Care panel has proposed the use of comprehensive testing using the combination of snap frozen tissue-based immunohistochemistry/immunofluorescence (IHC/IFA) assays followed by confirmatory fixed or live CBA and/or immunoblots, depending on the antigen/s. Although the snap frozen rat brain IHC/IFA offers excellent sensitivity and specificity for screening multiple AE/PNS Abs simultaneously, however, due to the complex and labor-intensive protocol (7-day protocol; brain-extraction, fixation, cryopreservation, snap-freezing, and cryo-sectioning) they are currently available in only a few highly specialized neuroimmunology laboratories. In contrast, some clinical laboratories use commercial fixed rat brain sections and CBA kits for detecting AE/PNS AAbs; however, these kits have variable sensitivity and specificity. In this roundtable, we will provide a detailed overview of the lab workflow including in-house preparation of snap-frozen rat brain sections and various testing methodologies used to test NAbs in AE/PNS. We will also present some practical examples to familiarize participants with recommended testing algorithm in suspected pediatric and adult cases and the result interpretations. Finally, we will discuss our recommendations on how to choose the right lab test panel/s and which matrix should be send for testing (e.g. CSF or serum or both).

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Determine a comprehensive disease-based algorithm for testing NAbs in AE/PNS.
  2. Identify the laboratory workflow using rat brain IHC/IFA assay in combination with confirmatory testing.
  3. Discuss the AAb panel/s to choose from and when to send serum or CSF or send both.

R7: Validation and monitoring of pneumatic tube systems


Yun Huang, Kingston Health Sciences Center, Kingston

Pneumatic tube systems (PTSs) have been implanted widely in modern hospitals to efficiently and reliably transport blood samples from clinical units to medical laboratories. However, the quality of blood samples delivered by PTSs may be compromised, as reported in many studies. One common concern is the hemolysis of blood samples induced by the acceleration in PTSs. Hemolysis falsely increases the concentrations of certain analytes, such as potassium and lactate dehydrogenase, because their concentrations in blood cells are much higher than in serum or plasma. In addition, hemoglobin released during the process of hemolysis may interfere with the measurement of assays. There are numerous challenges associated with the validation and monitoring of PTSs in current laboratory practice. Although the validation and monitoring of PTSs have been included in the quality management requirements, corresponding practice guidelines have not yet been made available. Traditionally, blood samples from heathy volunteers are used for validation and monitoring purposes, but their source is limited, and they may not adequately represent the quality of blood samples collected from diverse patient populations. Moreover, the design and distribution of PTS routes further complicate matters, as they may vary significantly among hospitals. PTSs in different hospitals may contain dozens or even hundreds of routes connecting clinical unites to laboratories.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Discuss accreditation requirements.
  2. Identify available material or tools.
  3. Discuss primary protocols.


R8: Quality Improvement and Patient-Centered Care: Best Practice Guidelines for Medical Error Disclosure in Canada


Jay Kalra, Royal University Hospital, Saskatoon

The prevalence of medical errors in healthcare systems has significantly compromised the quality of healthcare delivery. Prioritizing patient safety and system improvement over punitive measures for healthcare providers is crucial to address the emerging concern of healthcare quality worldwide. The emerging concern for healthcare quality worldwide persists despite efforts to minimize adverse events and medical errors. We have previously reported that international policies and the Canadian Provincial College of Physicians and Surgeons both encourage the open disclosure of adverse events and have suggested its integration into a ‘no-fault’ model. Disclosure policies can provide a framework and guidelines for appropriate disclosure, leading to more transparent practices. The issue of honest disclosure of a medical error to the patient or their family has been relatively unattended. We have also evaluated medical error disclosure policies based on the inclusion of the following key points: an apology or expression of regret, some form of patient support, avoidance of blame, provider support, and avoidance of speculation. Effective communication between health care providers, patients and their families throughout the disclosure process is integral in sustaining and developing the physician patient relationship. The complexities of medical error disclosure to patients present ideal opportunities for medical educators to probe how learners are balancing the ethical complexities involved in error disclosure with other related fields. Designing best practice error disclosure policy requires integrating many aspects, including bioethics, physician-patient communication, quality of care, and team-based care delivery. We suggest implementing a uniform national policy that addresses errors in a non-punitive manner and respects the patient’s right to an honest disclosure. Not only should disclosing medical errors be a routine part of medical care to enhance quality improvement, but it would also protect patients’ health and autonomy.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Define the concept of medical error, quality care/patient safety in health care.
  2. Identify magnitude, scope and epidemiology of medical error in health care and laboratory medicine.
  3. Identify dilemma of error/adverse event and ethical issues: the concept of disclosure.
  4. Discuss current national and international disclosure policies.
  5. Examine Canadian provincial and territorial health region policies and guidelines.


R9: Lessons in the long run: hyponatraemia in marathon runners


Robert Moore, Canadian Memorial Chiropractic College, Toronto

Based on dubious research long distance runners were advised to hydrate during competition. This has led to at least a dozen deaths from collapsed marathon runners being medically treatment inappropriately. For those who survive there may be irreversible brain damage due to extrapontine demyelination. Laboratory measurements can have a significant role in differential diagnosis and minimizing the risks of improper treatment. Guidelines have been developed for safer hydration during distance events. This has implications for the treatment of hyponatraemia in hospitalized patients. The incidence of this is said to be of the order of 20-30% in the USA. Even moderate hyponatraemia has an effect on activities of daily living leading to hospitalization. Surgery, some common drugs and infections can worsen hyponatraemia to a dangerous extent. The presenter welcomes hearing of your experience and opinions on this topic.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Identify at what level would the clinician expect to see the symptoms of hyponatraemia? There are acute and chronic forms of the disease.
  2. Explain pseudo hyponatraemia – a laboratory error seen with direct electrode measurement of plasma sodium.
  3. Discuss possible causes of hyponatraemia and laboratory support for differential diagnosis.
  4. Describe damage caused by hyponatraemia, especially extrapontine demyelination.
  5. Discuss laboratory support to minimize the risks of inexpert treatment.


R10: Cases in Pediatric Clinical Biochemistry


Lawrence de Koning, University of Calgary and Alberta Precision Labs, Calgary

Pediatric clinical biochemistry is an extremely stimulating area of laboratory medicine. The dynamic, ever-changing physiology of children can lead to surprising and unusual results which can challenge the comfort levels of clinical biochemists. This roundtable will review several cases identified during review of critical results at the Alberta Children’s Hospital Rapid Response Laboratory. These cases will focus on laboratory errors, analytical interferences and rare conditions leading to unusual results in children. This roundtable seeks to generate interest and awareness about pediatric clinical biochemistry, and pediatric lab medicine in general.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Discuss unusual pediatric clinical biochemistry cases identified by review of critically high and low patient results from an acute care pediatric clinical biochemistry laboratory.
  2. Review stages of the testing process that can cause unusual results.
  3. Describe unique physiologic aspects of children and rare pediatric conditions that can cause unusual results.


R11: Cannabis, alcohol, inflammasome


Manuela Neuman, University of Calgary and Alberta Precision Labs, Calgary

This roundtable summarizes the recent findings on the role of cannabinoid receptors, their synthetic or natural ligands, as well as their metabolizing enzymes in normal gastrointestinal (GI) function and its disorders, including irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and possible adverse events. The synergism or antagonism between Cannabis’ active ingredients and the “entourage” plays a role in the efficacy of various strains. Some elements of Cannabis may alter disease severity as over-activation of Cannabis receptors CB1 and CB2 can lead to changes of the commensal gut flora. The endocannabinoid system (ECS) contributes to gut homeostasis. The ability of ECS to modulate inflammatory responses demonstrates the capacity of ECS to preserve GI function. Alterations of the ECS may predispose patients to pathologic disorders, including IBD. Clinical studies in IBD demonstrate that subjects benefit from Cannabis consumption as seen through a reduction of the IBD-inflammation, as well as through a decreased need for other medication. Metabolic fatty liver disease (MFLD) is characterized by fat accumulation in the liver. The occurrence of inflammation leads to metabolic-steatohepatitis (MASH). The use of Cannabis might reduce liver inflammation. Conclusions: With limited evidence of efficacy and safety of Cannabis in IBD, IBS, and MAFLD, Cannabis has been used for its medicinal intentions since ancient times. Its use leads to the activation of Cannabis receptors CB1 and CB2 that, through specific mechanisms can prime to change of inflammation or repair. The novel results are linked to the medical use of Cannabis in GI system. However the people that use cannabis and misuse alcohol exposed themselves to serious adverse events. Our laboratory can assesw the use and misuse of alcohol and cannabis.

Learning Objectives – at the end of this roundtable participants will be able to:

  1. Explain the role of cannabis consumption in GI system and present cases of inflammation and repair.
  2. Discuss the information on the function of Cannabis in metabolic fatty liver disease and alcohol-misuse induced liver damage.
  3. Discuss laboratory data on cannabis, alcohol and inflammasome.

W1: A night with Venus without a lifetime with Mercury: Improved access to syphilis testing through community-based POCT


Anna Fuezery, Alberta Precision Laboratories, Edmonton, AB; Department of Laboratory Medicine and Pathology, University of Alberta, Edmonton

Allison Venner, Alberta Precision Laboratories, Calgary, AB; Department of Pathology & Laboratory Medicine, University of Calgary, Calgary

Syphilis is a highly infectious, sexually transmitted disease. Primary syphilis typically presents as a single, painless ulcer at the site of inoculation 2-6 weeks after infection. If left untreated, the infection progresses through several stages that have more severe symptoms and sequelae. In 15-40% of untreated cases, the disease progresses to involve the central nervous system, heart, or other organs. Congenital syphilis leads to stillbirth in 20% of cases; in live births it may cause severe clinical manifestations in the newborn. Historical treatments for syphilis included guaiacum, mercury, and arsenic, but they were ineffective and/or extremely toxic. The advent of penicillin in 1943 was a turning point in disease treatment due to its high efficacy, minimal side effects, and ease of availability. Cases of infectious and congenital syphilis have skyrocketed in Canada since 2017. According to the Public Health Agency of Canada, the rate of infectious syphilis increased by 166% between 2017 and 2021. In the same period, the incidence of congenital syphilis increased by 1,271% from seven cases in 2017 to 96 in 2021. Many recent syphilis cases have occurred among populations who are street-involved or live in rural and remote communities; they are challenging to reach through standard healthcare services. Point-of-care testing (POCT) for syphilis provides immediate access to testing and results, which enables same-visit treatment, reduces complications, eliminates further transmission, and reduces the number of future healthcare visits. The first point-of-care syphilis test approved by Health Canada became available in 2023. The overall goal of this workshop is to enable participants to successfully implement and support point-of-care syphilis testing in their jurisdiction. The workshop will consist of presentations, question-and-answer (Q&A) periods, and an interactive audience activity to address three main topics:

  • Topic 1: Introduction to syphilis (origins, stages of infection, past and present treatment modalities, public health reporting, linkage to HIV)
  • Topic 2: Diagnostic tests for screening and diagnosis (serology testing, POCT)
  • Topic 3: Design, implementation, and maintenance of a POCT quality assurance program (training, competency, quality testing, patient testing, result reporting, collaboration with public health)

Learning Objectives – at the end of this workshop participants will be able to:

  1. Describe the stages of syphilis infection, current treatment modalities, public health reporting requirements, and the relationship with HIV co-infection.
  2. Compare and contrast diagnostic tests available in Canada for screening and diagnosis of syphilis, including serological testing and POCT.
  3. Design a strategy for the development, implementation, and maintenance of a POCT quality assurance program for syphilis.


W2: Does your data support your reference intervals?


Dana Bailey, Mount Sinai Hospital, Toronto

Matthew Lafreniere, Sunnybrook Health Sciences Centre, Toronto

Albert Tsui, Alberta Precision Laboratories, University of Alberta, Edmonton

In an era of evidence-based medicine and patient access to laboratory reports, the accuracy of reference intervals is increasingly important. However, many laboratories still maintain historical reference intervals for which the accuracy and suitability has not been objectively evaluated. Seeing that the development of reference intervals lies with the laboratory director and/or designate, clinical biochemists should understand the means by which reference intervals can be developed, evaluated, and implemented. During this interactive session, we will review various strategies to validate and verify reference intervals, with a focus on indirect, data-driven approaches. We will touch on the current CLSI recommendations for reference interval validation and verification and highlight the pros and cons of each. Depending on publication availability, we will review the new CLSI guideline on reference interval verification. Through hands-on tutorials, we will explore tools of varying complexity including online reference interval calculators (Kosmic), Excel-based worksheets (will be provided to participants), EP Evaluator, and refine R. Finally, we will discuss implementation strategies, including change management tools, assessment of flagging rates, stakeholder engagement and education, and others. In total, this workshop will assist laboratory professionals with developing an efficient and effective means of validating and verifying the reference intervals used by their laboratory. Participants are encouraged to bring their own data and must bring a laptop. Verification of the harmonized reference intervals proposed by the CSCC Working Group on Reference Interval Harmonization will be used for this workshop.

Learning Objectives – at the end of this workshop participants will be able to:

  1. Critically assess current CLSI standards for reference interval validation and verification.
  2. Practice using direct and indirect reference interval validation and verification tools.
  3. Explore strategies used to implement revised reference intervals.


W3: Interpretation of urine drug testing: From screen to confirmation


Jessica Boyd, University of Utah/ARUP Laboratories, Salt Lake City

Most clinical laboratories run some form of urine drug testing, which may range for immunoassay screens to multi-analyte mass spectrometry panels. However, interpretation of these tests is complex requiring consideration of many factors including analytical methodology, assay specificity, metabolite patterns, and windows of detection. An additional challenge is an ever changing pharmaceutical and illicit drug landscape. Proficiency in drug testing interpretation is an important skill for laboratorians, not only to keep on top of changing drug trends but to also provide interpretive consultation to clinicians. This workshop will review the fundamentals of urine drug testing interpretation including discussion of drug classes commonly requested for drug testing. Analytical methodologies will be reviewed including impacts of crossreactivity, cutoff selection and analyte hydrolysis. The last portion of the workshop will be devoted to working through series of urine drug testing interpretation cases drawn from real life examples.

Learning Objectives – at the end of this workshop participants will be able to:

  1. Discuss classes of drugs commonly included in urine drug testing including metabolite patterns, pharmaceutical formulations, and emerging drug classes.
  2. Review the strengths and limitations of common immunoassay and mass spectrometry techniques used in urine drug testing.
  3. Analyze drug screen interpretive questions commonly encountered in the clinical laboratory.

Laboratory test results are central in a majority of healthcare decisions. Obtaining these precious data can be as simple as clicking in the system or checking a box on a requisition, right? However, even if the financial, material, and human resources were limitless, inconsiderate use of diagnostic laboratory testing leads to undue waste and can have negative clinical consequences. This symposium will focus on practical strategies laboratory professionals can put into action to optimize use of our raw material, the patients’ blood, and to ultimately improve care.

Learning Objectives – at the end of this symposium participants will be able to:

  1. Discuss recommendations regarding appropriate laboratory test utilization.
  2. Explain the impact of repeated blood draws in hospitalized patients and underline intervention strategies.
  3. Discuss the impact of reflex testing and test interpretation by laboratory professionals.

Laboratory Sustainability in 2024: The right test, for the right patient, at the right time

Daniel Beriault, Unity Health Torontom University of Toronto, and Li Ka Shing Knowledge Institute, Toronto

The push for laboratories to improve on sustainability practices and become more ‘green’ is ever growing. Appropriate laboratory utilization, or “Choosing Wisely”, is an excellent tool to leverage not only to improve test utilization and blood conservation, but also to improve on our lab’s sustainability and carbon footprint. The COVID-19 pandemic taught us the importance of conversation during laboratory supply chain disruptions, and in some ways demonstrated the amount of unnecessary waste that was occurring. The CSCC membership recently developed a number of Choosing Wisely Canada recommendations and guidance statements to further improve lab utilization. The question is, how do we build on our efforts and lessons learned to further improve lab sustainability?

Learning Objectives – at the end of this presentation participants will be able to:

  1. Describe the role of the clinical biochemist in laboratory sustainability.
  2. Relate the latest efforts by the CSCC membership to advance lab utilization.
  3. Discuss what other societies or countries are doing to improve utilization and sustainability.

The added value of reflective testing – experiences from The Netherlands

Wilhelmine Verboeket-van de Venne, Zuyderland Medical Centre, Heerlen/Sittard-Geleen, The Netherlands

Reflective testing is a procedure in which the laboratory specialist can decide to add one or more tests to a laboratory request, after inspection of (reflection on) the results Other available (medical) information is taken into account and in some cases an interpretation is added to the report. This procedure is different from reflex testing, in which tests are added automatically, after predefined conditions are met. Reflective testing can be very useful for the physician requesting the blood sampling. Especially when it concerns unexpected pathology or pathology outside the normal scope of physicians. The procedure of reflective testing will be illustrated in detail, including examples from daily practice. Furthermore, physicians opinions and benefits for the patient will be discussed.

Learning Objectives – at the end of this presentation participants will be able to:

  1. Explain the procedure of reflective testing.
  2. Outline how to start with reflective testing.
  3. Discuss learning experiences with reflective testing in the Netherlands.

Taking Less Blood from Patients: Why it is critically important and how you can help

Jeannie L. Callum, Kingston Health Sciences Centre and the Department of Pathology and Molecular Medicine, Queen’s University

Iatrogenic anemia is common in a hospital setting with approximately 40% of ICU patients receiving a red blood cell transfusion. Transfusions are costly, in scarce supply and have associated health risk. Patient treatment and management decisions are tied to blood-based laboratory diagnostics, which requires frequent blood draws in particular in an ICU setting. The STRATUS Randomized Clinical Trial was a multi-centre Canadian study that demonstrated the positive impact on patient care in collecting less blood in the ICU. This session will describe a successful hospital-wide implementation of the low volume tubes as an opportunity for the learners to consider embarking on this change.

Learning Objectives – at the end of this presentation participants will be able to:

  1. Discuss the importance of reducing number and volume of draws for transfusion.
  2. Explain the evidence in implementing blood tubes that collect less blood.
  3. Support the implementation of lower volume blood tubes.

CSCC-SQBC 2024 is held under the auspices of IFCC
