What is a PROTEIN C FUNCTIONAL?

Protein C Functional is a blood test that measures the activity of Protein C, a natural anticoagulant that helps regulate blood clot formation. The test is needed to evaluate suspected Protein C deficiency, which can increase the risk of abnormal blood clots, particularly venous thrombosis. It may be recommended in individuals with unexplained or recurrent blood clots, thrombosis at a young age, or a family history of clotting disorders.

FAQs

What is Protein C?

Protein C is a vitamin K-dependent protein produced mainly by the liver. When activated, it helps control clotting by inactivating certain clotting factors.

What does a low Protein C activity mean?

Low Protein C activity may indicate Protein C deficiency or may occur temporarily with certain illnesses, liver disorders, vitamin K deficiency, or anticoagulant treatment.

What is Protein C deficiency?

Protein C deficiency is a condition in which Protein C levels or activity are lower than expected, potentially increasing the tendency to develop abnormal blood clots.

Can Protein C deficiency be inherited?

Yes. Some cases are caused by inherited changes in the PROC gene and may run in families. Other cases are acquired due to medical conditions or medications.

What types of blood clots are associated with Protein C deficiency?

Protein C deficiency is particularly associated with an increased risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism.
