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.

1 row held back from this comparison

It is priced below $1 or below a tenth of the national median for code 85730 ($48.56). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
