Protein C Activity Functional near me in Greater Noida









The Protein C Activity Functional test measures the activity of protein C, a natural anticoagulant in the blood. It helps assess the risk of abnormal blood clot formation and is commonly used in evaluating unexplained or recurrent clotting disorders. This test is widely available in Greater Noida with Tata 1mg labs at an affordable price.
The Protein C Activity Functional test may be recommended for individuals with unexplained or repeated blood clots, recurrent miscarriages, or a family history of clotting disorders (thrombophilia). It also helps distinguish whether protein C deficiency is inherited or acquired due to conditions such as liver disease, vitamin K deficiency, severe infections, or use of anticoagulant medications like warfarin. By measuring protein C activity, this test provides key information for diagnosing clotting disorders and planning suitable treatment.
For the Protein C Activity Functional test, with prior approval from the doctor, discontinue heparin 1 day before and oral anticoagulants 7 days before testing, as these drugs may interfere with results. A duly filled coagulation requisition form (Annexure - CR/05) is required for sample collection. Overnight fasting is preferred, but not mandatory. Providing complete clinical details and medication history or a doctor’s prescription is essential for accurate interpretation of results.








What does Protein C Activity Functional measure?
The Protein C Activity Functional test assesses the functional activity of Protein C, a natural anticoagulant that helps blood clot regulation. Protein C functions by inactivating some of the clotting factors, thus averting excessive or abnormal clot formation in the blood.
Low activity of protein C can be due to either an inherited (genetic) or acquired deficiency, such as liver disease, vitamin K deficiency, severe infection, or the use of certain drugs like warfarin. People with protein C deficiency may have a greater risk of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE).
Conversely, normal protein C activity indicates that the body's clot-controlling mechanism is operating efficiently, with the result that there is a balanced rate of clotting and the breakdown of clots.
