Understanding Lab Tests for Hemorrhage
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Hemorrhage refers to significant bleeding that can occur internally or externally due to injury, medical conditions, or surgical procedures. While the diagnosis of active bleeding is typically made through clinical observation and imaging when necessary, blood tests play a crucial role in evaluating the body's clotting function and monitoring the effects of blood loss.
Recommended Test
Fibrinogen Activity
This test measures fibrinogen activity, a critical protein essential for blood clot formation. During significant bleeding or hemorrhage, fibrinogen levels can decrease as the protein is consumed in the clotting process to stop bleeding. Lower fibrinogen levels may also indicate an underlying bleeding disorder, making this test vital for both diagnosing clotting abnormalities and monitoring the body's response during active hemorrhage.

Why Blood Testing is Essential for Hemorrhage
During a hemorrhage, the body's natural clotting mechanisms are activated to stop the bleeding. Blood tests are fundamental for assessing how well these clotting systems are functioning, identifying potential bleeding disorders, and monitoring the consumption of clotting factors during active bleeding episodes.
Understanding Your Results
Fibrinogen activity levels help healthcare providers understand whether your blood can clot properly and if clotting factors are being depleted during bleeding episodes. This information is crucial for determining appropriate treatment strategies and monitoring recovery.
