Understanding Lab Tests for Bleeding Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Bleeding disorders are conditions that affect the blood's ability to clot properly, leading to prolonged or excessive bleeding. These disorders can be inherited or acquired and require specialized blood tests to diagnose and monitor effectively.
Recommended Test
Fibrinogen Activity
This test measures fibrinogen activity using the Clauss method, which assesses how effectively fibrinogen converts to fibrin during blood clot formation. Low Clauss levels indicate slower clot formation due to reduced fibrinogen levels, which can signal an increased risk of bleeding disorders and help identify clotting abnormalities.

How Blood Tests Diagnose Bleeding Disorders
Blood tests are the primary diagnostic tools for identifying bleeding disorders. These tests measure various components of the blood clotting system, including proteins, platelets, and clotting factors that work together to stop bleeding when an injury occurs.
Understanding Your Results
Abnormal fibrinogen activity levels can indicate various bleeding disorders, from mild clotting deficiencies to more serious conditions. Your healthcare provider will interpret these results in conjunction with your symptoms and medical history to determine the appropriate treatment approach.
