Fibrinogen concentration (mass concentration) in plasma

Why is this test done?

Your healthcare provider may order this test to check for blood clotting disorders, monitor conditions like liver disease (which can affect fibrinogen production), or evaluate bleeding risks before surgery. It can also help assess how well treatments for conditions like clotting disorders are working.

What does a result mean?

Results are not provided with specific reference ranges here, as they can vary by lab and medical context. Your results will be interpreted by your healthcare provider based on your overall health and medical history.

Sample preparation and timing

This test uses a blood sample drawn from a vein. If you’ve taken medications or supplements that affect clotting (like warfarin or aspirin), let your provider know. For best accuracy, avoid eating or drinking for a short period before the test, but follow your provider’s specific instructions.

Common conditions or treatments affecting results

Fibrinogen levels can be influenced by liver disease, infections, pregnancy, or certain medications. Conditions like multiple myeloma or severe burns may also affect fibrinogen levels. Your provider may adjust your treatment if fibrinogen is unusually low or high.
