The Protein S Activity Functional test measures the activity of protein S, a natural anticoagulant protein in the blood. It helps evaluate the risk of abnormal blood clot formation (thrombosis) and is commonly used in the workup of unexplained clotting disorders. This test is widely available with Tata 1mg labs at an affordable price in Noida.
The Protein S Activity Functional test is often recommended for those with unexplained or repeated blood clots, recurrent miscarriages, or a family history of clotting problems. It can also help identify whether protein S deficiency is inherited or acquired due to conditions such as liver disease, pregnancy, certain infections, or the use of medications like warfarin. By measuring protein S activity, this test provides important information for diagnosing clotting disorders and planning the right treatment.
For the Protein S Activity Functional test, with prior approval from the treating doctor, discontinue heparin 1 day before and oral anticoagulants 7 days before the test, as these medications can interfere with test results. A completed coagulation requisition form (Annexure - CR/05) is required for sample collection. While overnight fasting is preferred, it is not mandatory. Additionally, please provide complete clinical details along with the medication history or a doctor’s prescription, as this information is vital for proper interpretation and correlation of the test results.
