About this test

This profile measures the time your blood takes to clot through two different pathways. It is required before most surgery and is the routine monitoring test for anyone taking warfarin, where the INR must be kept inside a narrow target range.

What it measures

  • Prothrombin time and INR
  • Activated partial thromboplastin time

A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
