Frequently Asked Questions
What does Factor X Activity measure?
It measures the functional clotting ability of Factor X (Stuart-Prower factor), a vitamin K-dependent coagulation factor essential for the common pathway of blood coagulation.
Why is this test ordered?
It is used to evaluate bleeding disorders, monitor warfarin or direct oral anticoagulant therapy, assess liver synthetic function, and investigate prolonged PT/aPTT results.
Does Factor X Activity require fasting?
No, fasting is not required. The test can be performed on a citrated plasma sample collected at any time of day.
What causes low Factor X Activity?
Low levels may result from vitamin K deficiency, liver disease, warfarin therapy, disseminated intravascular coagulation (DIC), or rare inherited Factor X deficiency.
How is the sample collected?
Blood is drawn into a light blue citrate tube (3.2% or 3.8% sodium citrate) and must be filled to the correct volume for accurate coagulation testing.
