Partial Thromboplastin Time Blood Test (aPTT, PTT )

  • CLIA Certified Labs
  • Best Price
  • Digital Report

The Partial Thromboplastin Time (PTT) test is used to measure how quickly a person's blood clots.

  • Sample Type: Blood
  • Results: 1-5 days
  • Age: 18+

This test evaluates coagulation factors which are involved in the body's blood clotting process. If the PTT is prolonged, one or more of these factors may be deficient or inhibited.

The PTT test may be ordered when a person has unexplained bleeding or bruising, a blood clot or conditions such as liver disease which can effect the normal blood clotting process. People taking the anticoagulant Heparin to treat or prevent blood clots often use the PTT to monitor the effects of their dosage. This test is often ordered prior to having surgery to ensure a person does not suffer from a bleeding disorder.

No special preparation required.
