About prothrombin time (blood clotting test)

CPT 85610 is a prothrombin time (PT), usually reported with INR. It measures how quickly blood clots and is used to monitor warfarin therapy, to check liver function and before surgery. It is a single blood test.

What the price covers

The laboratory analysis only. The blood draw is a separate small charge. Patients on warfarin often have this test monthly, so the price matters more than it looks; finger-stick INR at an anticoagulation clinic or at home is often cheaper.

Why prices vary

A PT/INR costs a laboratory very little to run, yet hospital list prices range from single digits to well over $100. For recurring tests, independent laboratories and anticoagulation clinics are usually far cheaper than hospital labs.

Questions to ask

  • What is the self-pay price for 85610 and the draw fee?
  • If I need this monthly, is there a cheaper standing arrangement?
  • Can I use a home INR meter instead?
