Partial Thromboplastin Time Blood Test, Activated
A Partial Thromboplastin Time (PTT) Test assists in determining the ability of your body to form blood clots.
A partial thromboplastin time (PTT) test will help determine your body's capability to form blood clots. A blood clot forms following the successful and timely completion of a sequence of events known as the coagulation cascade, in which coagulation factors are activated one after the other. For the process to work effectively, an adequate quantity of each coagulation factor must be present, and each must function properly.
Symptoms that might lead to one ordering this test are, but not limited to, the following:
- easily bruised
- painful or swollen joints
- frequent or heavy nosebleeds
- blood in the urine
- heavy or prolonged menstrual periods
