What it is
The partial thromboplastin time (PTT or aPTT) test measures how long it takes blood to clot through a different pathway than the PT test. It is used to check for bleeding disorders, before surgery, and to monitor heparin.
What the price covers
The price usually covers the PTT test. The blood draw is often billed separately.
