Protein S

What is Protein S?
Protein S is a vitamin K-dependent protein that plays a critical role in the regulation of blood clotting. It functions as a natural anticoagulant in the body.

Role in Coagulation Control
Protein S enhances the activity of Activated Protein C (APC), which inactivates clotting factors Va and VIIIa. This action helps to prevent excessive clot formation and supports balanced blood flow.

Clinical Importance of Protein S
Deficiency or dysfunction of Protein S can lead to an increased risk of abnormal blood clotting, such as deep vein thrombosis or pulmonary embolism, and is often evaluated in patients with unexplained thrombotic events.

Private Protein S Testing in Slough and Surrounding Areas
Comprehensive coagulation testing, including Protein S levels, is available in Slough, Windsor, Maidenhead, and nearby Berkshire areas. This test is essential for assessing clotting risk and managing inherited or acquired thrombophilia.
