What it is

The prothrombin time (PT) test measures how long it takes blood to clot, and is reported with the INR, a standardized number. It is used to monitor warfarin and to check clotting before surgery or with liver disease.

What the price covers

The price usually covers the PT and INR result. The blood draw is often a separate charge; a fingerstick home or clinic INR check may be billed differently.
