APTT

What Is the Partial Thromboplastin Time (PTT/aPTT) Test?

The Partial Thromboplastin Time (PTT), also known as Activated Partial Thromboplastin Time (aPTT), is a blood screening test used to assess the body’s ability to form blood clots properly. It plays a crucial role in identifying clotting disorders and monitoring certain blood-thinning therapies.

How the Test Works

The test measures the number of seconds it takes for a blood sample to clot after specific reagents are added in a laboratory setting. This evaluation helps determine whether the clotting process is functioning as it should.

Why Is the PTT/aPTT Test Important?

The PTT/aPTT test is commonly used to:

Diagnose bleeding disorders

Evaluate unexplained prolonged bleeding or bruising

Monitor patients on anticoagulant therapy such as heparin

Assess clotting factor deficiencies and lupus anticoagulant presence
