Protein S Activity Test in Riverside, California

Same day and Affordable Protein S Activity Test, Locations Nationwide

Request A Test offers this convenient and affordable Protein S Activity Test in Riverside, CA. This test measures Protein S Activity, also called Functional Protein S. It measures the function or activity of a person's protein S. Protein S is one of 2 proteins that work together to regulate the formation of blood clots. Protein S along with Protein C helps ensure proper clotting to stop bleeding when the body is injured as well as ensuring that excessive unnecessary clotting does not take place. If protein S function is low, there's an increased risk of developing irregular blood clots. A deficiency in Protein S can be due to an inherited condition or caused by underlying disorders such as liver disease, kidney disease, cancer or severe infection. Measuring both the quantity and function of the protein can help differentiate between different types of disorders.

Protein S testing is often ordered when a person has unexplained recurrent blood clots or has a family history of blood clotting disorders. A Protein C Activity is often ordered along with Protein S. We also offer a Protein S Deficiency Panel which includes measurements for both the level and activity of protein S. A Protein C and S Panel which evaluates both is also available.
