This test measures the activity of Factor X, a key enzyme that activates thrombin formation in the common coagulation pathway.
Diagnostic Value: Low levels can result from liver disease, vitamin K deficiency, or inherited Factor X deficiency; high levels may contribute to thrombotic risk.
Clinical Significance: Often used to evaluate bleeding disorders or monitor anticoagulant therapy (especially direct Factor Xa inhibitors).
Symptom Correlation: Patients may experience nosebleeds, gum bleeding, or deep vein thrombosis.
The Factor X Activity test is critical in assessing clotting efficiency and anticoagulant response.
