What is this test? A coagulation factor test is used to find out if you have a problem with any of your clotting factors that may cause too little or too much blood clotting.
Sample required: Blood collected from a vein.
Tests done under this profile include:
- Clotting time.
- PT/INR
- APTT
- D-Dimer
- Fibrinogen.
Client preparation: No specific client preparation protocol is required. Inform your vaccinator if you are on any medications or have any underlying medical conditions or allergies before undergoing this test.
Turn-around time (How long does it take?): 2 hours offsite in a lab.
Basis of the Test: Clotting disorders can cause a dangerous amount of bleeding or clotting. If your doctor suspects you have a clotting disorder, they may recommend one or more coagulation tests. These tests measure various proteins and how they function.
Conditions that can cause coagulation problems include:
- Liver disease
- Thrombophilia, which is excessive clotting
- Hemophilia, which is an inability to clot normally
- Coagulation tests are useful in monitoring people who take medications that affect clotting ability.
- Coagulation tests are also sometimes recommended before surgery.
