The compendium of newly emerging and currently available hemophilia and anticoagulant treatments, while offering new choices for improved patient care, can create significant levels of interference with routine and specialized laboratory coagulation assays. Our new educational session will examine the interference in coagulation tests from presence of the direct oral anticoagulants (DOACs) and the extended half-life (EHL) and non-factor products. It is important for laboratories to be aware of how both classes of these products, when present, can impact downstream results and clinical decision making.  

Upon completion of this session, participants will be able to:
1. Identify how to detect DOAC’s with routine coagulation tests and how they impact results.
2. Understand how the new EHL products for hemophilia A and B perform in relation to the laboratory’s coagulation reagents.
3. Increase awareness of the impact of these issues on coagulation testing.

Standardization and harmonization of coagulation testing methods have come a long way in the last 3 to 4 decades; however, standardization is imperfect.  Laboratory professionals need to recognize the limitations of some of our most commonly used coagulation tests.  The INR system has harmonized prothrombin time across methods and platforms for the purpose of monitoring warfarin, but the system does not harmonize very high INR values nor does it harmonize INR values in the setting of liver disease.  Many hospital-based laboratories perform a one stage factor VIII assay to support a wide range of clinical indications.  In the last decade, important biases have been demonstrated between one stage assays and chromogenic assays when diagnosing hemophilia A patients or monitoring new hemophilia therapies.  Finally, quantitative D-dimer assays have excellent negative predictive value to exclude venous thromboembolism.  Unfortunately, there is a lack of standardization, and even a lack of a standardized unit of measure.  Implementation of D-dimer requires careful attention to both the unit of magnitude and the unit type, especially when using different instrumentation across a laboratory system.

Learning Objectives:

• Recognize limitations of INR system
• Choose appropriate factor VIII and factor IX assays for various clinical indications
• Identify potential safety issues created by nonuniform D-dimer units and lack of standardization

D-dimer is used in the clinical evaluation of suspected venous thromboembolism (VTE). Newer measurement methods show high sensitivity for this test, and in combination with pretest probability assessment, have a high negative predictive value for exclusion of VTE, obviating the need for many imaging procedures, optimizing healthcare resource utilization. This presentation will highlight the evidence supporting the clinical utility of D-dimer in VTE: upper extremity, lower extremity, recurrent lower extremity DVT and pulmonary embolism. The American Society of Hematology 2018 updated clinical practice guidelines outlining an evidence-based strategy for the diagnostic evaluation of VTE will be reviewed.

Learning Objectives: 

• Review the measurement of D-dimer and sensitivity/specificity for the clinical evaluation of suspected venous thromboembolism.
• Describe the clinical utility of D-dimer in the diagnostic management of suspected upper extremity, lower extremity deep vein thrombosis, recurrent deep vein thrombosis and pulmonary embolism.
• Review the American Society of Hematology practice guidelines 2018 for the Diagnosis of Venous Thromboembolism.

Coagulation testing is commonly performed in hospital systems to screen for potential bleeding or thrombotic disorders. Examples of patient populations and clinical applications include outpatients presenting to the emergency room with signs of venous thromboembolism (VTE), perioperative screening to exclude the potential for bleeding during surgery, or to monitor inpatient anticoagulant treatment. Newly acquired coagulation testing instruments require an extensive validation process before being used for live patient testing in order to ensure quality of test results. Instrument validation can be especially challenging for different hospitals within a health network, due to different testing menus, volumes, and instruments used in these centers. The webinar will provide guidance on how coagulation testing instruments are validated, test results verified, and ensuring continuous quality during the life of the instruments.

Learning objectives:

• Describe the responsibility of the laboratory during the validation process of new instrumentation 
• Distinguish between validation and verification of laboratory instrumentation
• Present strategies for ensuring continuous quality of laboratory testing results on a daily basis, focusing on hemostasis testing

Laboratory testing for coagulation factor deficiencies and inhibitors is important for diagnosing and monitoring inherited and acquired coagulopathies and for evaluating the causes of coagulation screening test abnormalities. The webinar will cover strategies and pitfalls to consider and which assays should be performed to further evaluate test abnormalities, including assays for specific factor inhibitors. Real life cases, and illustrations of pre-analytical errors and interferences, will be used to illustrate important practice points. The different patterns and causes of abnormalities will be reviewed to ensure that laboratories consider all potential causes of abnormal findings.

Participants in this session will be able to:

• Differentiate which factor deficiencies are common and which are rare
• Describe what factor assays should be considered for a preoperative patient with a prolonged APTT, and which abnormalities are most common
• Describe how to test for a coagulation factor deficiency and a specific factor inhibitor
• Describe at least two pre-analytical errors that could cause test abnormalities that mimic a factor deficiency

Information will be presented in a case study format to highlight real-life case scenarios and how laboratories can handle and prevent future issues to ensure they can optimize their coagulation testing and patient care.

Objectives:

• Identify solutions in areas of coagulation that can be enhanced by implementing good laboratory practices and standard operating procedures
• Analyze real-life case studies and how to troubleshoot testing to determine root cause and steps to prevent reoccurrence.

Objectives:

• Identify the effects of direct oral anticoagulants on common  and other anticoagulation laboratory measures
• Describe common errors that are seen in practice when the effect of DOACs on common anticoagulation laboratory measures is not realized

This webinar will look at the principles of the assays available to monitor heparin.  The most frequent assay that is used is the activated partial thromboplastin time (aPTT).  This assay is readily available and inexpensive.  However aPTT reagents are poorly standardized and have different sensitivities to heparin. There is no dose response relationship with heparin.  Due to the analytical and biological variables of heparin, patients respond to it differently.  Laboratories using the aPTT to monitor heparin, need to provide clinicians with a heparin therapeutic range specific for their lot of reagent on their analyzer.  An anti-Xa assay is a standardized test that has good precision, and is linear. A heparin assay can provide clinicians with an assay that accurately determines heparin levels and can improve overall patient heparin management.

The objectives of this webinar are:

• Describe the principle of the aPTT and  heparin assays
• Identify the advantages of each assay and outcomes for patient care
• Enhance problem solving skills by analyzing data from case studies.
