Description:

Partial Thromboplastin Time (PTT) Blood Test

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

The PTT test is often ordered with a Prothrombin Time (PT) Test.  Results from both of these tests can help a person's doctor to differentiate between types of bleeding disorders and determine which types of further testing may be necessary.

Turnaround time for the PTT test is typically 1 business day.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

If Heparin is being administered by intermittent injection, specimen should be drawn 1 hour prior to next dosage.

This test is not appropriate for monitoring Unfractionated Heparin therapy.  If you are taking Heparin, please consult your doctor to determine if this test is appropriate.
