How I investigate for bleeding disorders

Area of Science:

• Hematology
• Clinical Pathology

Background:

• Laboratory investigations are crucial for diagnosing bleeding disorders based on patient history and initial findings.
• Suspected inherited or acquired bleeding disorders necessitate thorough laboratory evaluation.

Purpose of the Study:

• To present an updated, practical strategy for investigating common and rare bleeding disorders.
• To guide the ordering and reporting of diagnostic investigations for bleeding disorders.

Main Methods:

• Review of author's experience and recent literature on bleeding disorder diagnosis.
• Development of a diagnostic strategy considering clinical context and laboratory capabilities.

Main Results:

• A practical strategy is essential, considering clinical presentation, pretest probability, and laboratory resources.
• Simultaneous testing for von Willebrand disease, platelet function disorders, and coagulation defects is often beneficial.
• Investigation of rare bleeding disorders is indicated for unexplained severe bleeding events.

Conclusions:

• An organized diagnostic strategy is vital for confirming findings and interpreting results accurately.
• This framework aids in assessing both common and rare causes of bleeding disorders.
• Effective investigation leads to a confirmed diagnosis and appropriate patient care.
