Protein S Test — Coagulation Function

Introduction

Protein S is a vitamin K–dependent glycoprotein synthesized in the liver and a key component of the natural anticoagulant system. Protein S serves as a cofactor for Protein C, helping Activated Protein C (APC) degrade clotting factors Va and VIIIa, thereby preventing excessive clotting and maintaining blood flow balance.

Deficiency in Protein S reduces anticoagulant capacity and increases the risk of deep vein thrombosis (DVT) and pulmonary embolism.

Why Take a Protein S Test?

  • Thrombosis risk assessment: Protein S deficiency is a major cause of hereditary thrombophilia.
  • Coagulation monitoring: For patients with recurrent or unexplained thrombosis.
  • Family screening: Useful for individuals with early-onset or familial clotting disorders.
  • Disease evaluation: Protein S may decrease in liver disease, vitamin K deficiency, pregnancy, or oral contraceptive use.

Method & Workflow

A venous blood sample is tested for Protein S activity or antigen level. Results should be interpreted alongside Protein C, coagulation factors, and clinical context.

Who Should Consider Testing?

  • Patients with recurrent unexplained thrombosis
  • Young patients with DVT or pulmonary embolism
  • Individuals with a family history of thrombophilia
  • Pregnant women or those on long-term contraceptives/anticoagulants

Frequently Asked Questions (FAQ)

Q1: What’s the difference between Protein S and Protein C deficiency?
A: Both are anticoagulant proteins. Protein S acts as a cofactor for Protein C, and deficiency in either raises thrombosis risk.

Q2: Does Protein S deficiency always cause thrombosis?
A: Not always, but it significantly increases the likelihood of venous thrombosis.

Q3: What conditions can temporarily lower Protein S levels?
A: Pregnancy, oral contraceptive use, acute thrombosis, liver disease, and vitamin K deficiency can all lower Protein S.
