What this test is

Prothrombin Time (PT) with International Normalized Ratio (INR) and Partial Thromboplastin Time (PTT) are blood tests that evaluate the body's ability to form clots. They assess different parts of the coagulation cascade, a series of protein interactions that lead to blood clotting.

What it measures

  • Prothrombin Time (PT) — reflects the time it takes for blood to clot
  • International Normalized Ratio (INR) — standardizes PT results for comparison across different labs
  • Partial Thromboplastin Time (PTT) — measures how long it takes for blood to clot using a different pathway

What the test involves

A healthcare professional will collect a blood sample by inserting a needle into a vein, typically in your arm. The collected blood is then sent to a laboratory for analysis.

Why it is often ordered

Clinicians often order this test to monitor individuals taking anticoagulant medications, such as warfarin. It may also be used to investigate unexplained bleeding or clotting disorders.

Preparation

Follow any specific instructions provided by the laboratory where you will have your blood drawn. Some medications may need to be temporarily stopped before the test.

How results are reported

Results are typically reported within a few business days. Your results will include reference ranges, which are the expected values for healthy individuals, but these ranges can vary between laboratories.

Before you go

  • Confirm fasting requirements with the lab.
  • Verify if any of your current medications need to be stopped.
  • Ask about the expected turnaround time for results.
