Coagulation Factor Tests
Reviewed
Coagulation factor tests are blood tests that check one or more of your clotting factors to see if you have too much or too little of a clotting factor, are missing a clotting factor, or have a clotting factor that isn't working right. These tests help find out if you have a problem with any of your clotting factors that may cause too little or too much blood clotting.
Preparation and collection
You don't need any special preparations for a coagulation factor test.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- Your provider may need to order other tests to find the cause of a problem with your clotting factors.
- Results should be interpreted by a healthcare professional.
What to do next
Talk with your provider to find out what your test results mean and what treatment is best for you.
