Coagulation Function Profile (Plasma)

What This Test Measures

The test evaluates multiple clotting factors, including prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen levels, and possibly thrombin time or fibrin degradation products, depending on the lab’s specific panel. These measures help identify abnormalities in blood clotting pathways.

Common Conditions Monitored

This panel is often used to monitor conditions like bleeding disorders (e.g., hemophilia), clotting disorders (e.g., deep vein thrombosis risk), liver disease (which affects clotting factor production), or after treatments like anticoagulants (e.g., warfarin). It may also be used pre- and post-surgery to assess clotting risks.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in the arm. Plasma is separated from blood cells and used for testing. If you’re on anticoagulant medication, your doctor may adjust timing to ensure accurate results.

When You Might Need This Test

Your doctor may recommend this test if you have symptoms like excessive bleeding, unexplained bruising, prolonged bleeding after cuts, or if you’re at higher risk for clots (e.g., after surgery, heart disease, or long periods of immobility).
