Outpatient: lowest $5.94, median $60.00, highest $322.00 — a 54.2× difference within the same market.
As an inpatient, the same code is billed by 28 facilities here, median $73.15. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
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.
