PROTEIN S FUNCTIONAL / ACTIVITY (H180)
Also Known As:
Serum Protein S
Protein-S
Functional Protein S
About This Test
Protein S is a vitamin K dependent plasma glycoprotein produced in the liver. It acts as a necessary cofactor to activated Protein C in the proteolytic inactivation of procoagulant factors Va and VIIIa. Congenital Protein S deficiency is an autosomal dominant disorder seen in 1% to 3% of patients with venous thromboembolism. Heterozygous Protein S deficiency carriers have approximately 10 fold increased risk of venous thromboembolism. They are also predisposed to recurrent abortions, preeclampsia, intra uterine growth retardation & still births.

Frequently Asked Questions
Outsourced test are being done from Dr. Lal Path Lab. Charges and reporting time is same as of Dr. Lal Path Labs.
Overnight fasting is preferred. It is recommended that patient discontinues Heparin for 1 day and Oral Anticoagulants for 7 days prior to sampling as these drugs may affect test results. Discontinuation should be with prior consent from the treating Physician.
The Protein S Functional / Activity test is important because it evaluates how well Protein S is working as a natural anticoagulant, helping detect functional Protein S deficiency and assess the risk of abnormal blood clot formation (thrombophilia).
TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
