Protein S Activity Functional near me in New Delhi









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 New Delhi.
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.








What does Protein S Activity Functional measure?
The Protein S Activity Functional test measures the functional activity of protein S in regulating blood clotting.
- Low functional protein S activity suggests protein S deficiency (inherited or acquired), increasing the risk of abnormal clot formation.
- Normal activity suggests that protein S function is adequate.
