INR test for patients on anticoagulant medications to monitor clotting time.
A coagulation panel measures how well your blood clots — a critical balance between stopping bleeding and preventing dangerous clots. The panel typically includes PT/INR (prothrombin time, measuring the extrinsic clotting pathway), aPTT (activated partial thromboplastin time, measuring the intrinsic pathway), fibrinogen (the protein that forms the structural framework of blood clots), and D-dimer (a marker of clot breakdown that can indicate active clotting). These tests are essential for monitoring anticoagulant therapy (warfarin, heparin), evaluating unexplained bleeding or bruising, and screening for clotting disorders like Factor V Leiden or antiphospholipid syndrome.
Key Details
Who Is This For?
People taking blood-thinning medications (warfarin, heparin) who need regular monitoring. Anyone with unexplained bruising, prolonged bleeding, or a history of blood clots. Women with recurrent miscarriages, which can be caused by clotting disorders. People with a family history of deep vein thrombosis (DVT) or pulmonary embolism.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
