Problems and solutions in laboratory testing for hemophilia.

Area of Science:

• Hematology
• Clinical Pathology
• Laboratory Medicine

Background:

• Hemophilia A and B diagnosis requires clinical assessment and laboratory confirmation of factor deficiencies.
• Laboratory test results determine hemophilia severity and guide patient management and therapy selection.
• Inaccurate diagnoses or inhibitor detection can lead to inappropriate management and adverse patient outcomes.

Purpose of the Study:

• To outline problems in laboratory testing for hemophilia diagnosis and inhibitor detection.
• To provide strategies and solutions for overcoming challenges in hemophilia laboratory testing.
• To emphasize the importance of best practices and clinician vigilance in laboratory diagnostics.

Main Methods:

• Review of potential errors in the laboratory testing process for hemophilia, from pre-preanalytical to post-postanalytical stages.
• Identification of specific and general strategies to mitigate diagnostic and inhibitor detection errors.
• Emphasis on the integration of clinical assessment with laboratory findings.

Main Results:

• Laboratory testing is indispensable for diagnosing hemophilia A/B and characterizing disease severity.
• Errors can occur at any stage of the laboratory testing interface, impacting diagnosis and management.
• Proposed solutions include adopting best practices and clinician review of results in clinical context.

Conclusions:

• Improving hemophilia diagnosis necessitates addressing laboratory testing challenges.
• Adoption of best practices by all stakeholders (clinicians, phlebotomists, labs) is key.
• Clinicians must critically evaluate lab results alongside clinical history and consider repeat testing to prevent misdiagnosis.
