What is PROTEIN S ANTIGEN, FREE?

This test measures the amount of "free" Protein S in your blood, which is the active form not bound to other proteins. Protein S is a crucial protein that helps prevent blood clots. Assessing its free form provides a direct measure of its availability to function.

Why is this test important?

Free Protein S antigen levels are important for diagnosing Protein S deficiency, a condition that increases the risk of developing blood clots. It helps differentiate between different types of Protein S deficiency and guides appropriate management for patients with thrombotic tendencies.

How to Prepare

Fasting may be required. Please consult your doctor for specific instructions.
