The 5 tests in this panel
What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.
Prothrombin Time (PT)
How many seconds your blood plasma takes to clot in the lab. It checks several clotting proteins and is used to follow warfarin.
- Adults
- 9.4–12.5 seconds
INR (International Normalized Ratio)
A standard way to report how long your blood takes to clot, used mainly to monitor warfarin and to check clotting and liver function.
- Adults
- 0.9–1.1 INR
Activated Partial Thromboplastin Time (aPTT)
A clotting-time test that shows how many seconds your blood takes to clot, and is also used to monitor heparin treatment.
- Adults
- 25–37 sec
Fibrinogen Activity
Measures how much working fibrinogen, the protein that forms the mesh of a blood clot, is in your blood.
- Adults
- 200–393 mg/dL
Platelet Count
The number of platelets, the small blood cells that help your blood clot, in a sample of your blood.
- Adults
- 150–450 ×10³/µL
