This test measures the activity of Factor II, also known as prothrombin, which is essential for converting fibrinogen into fibrin during clot formation.
Diagnostic Value: Low levels may result from liver disease, vitamin K deficiency, or inherited Factor II deficiency; elevated activity may increase the risk of thrombosis.
Clinical Significance: It helps evaluate bleeding or clotting disorders and monitor anticoagulant therapy.
Symptom Correlation: Abnormal results can cause easy bruising, prolonged bleeding, or thrombotic events.
The Factor II Activity test supports diagnosis of both inherited and acquired coagulation abnormalities.
