Protein S Antigen Test in Naperville, Illinois

Same day and Affordable Protein S Antigen Test, Locations Nationwide

Request A Test offers this convenient and affordable Protein S Antigen Test in Naperville, IL. This test measures the Total and Free levels of Protein S Antigen. 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 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.

Free protein S is the portion of protein S antigen which is not bound to other proteins on the blood. Measuring both total and free levels can help to differentiate the type of protein deficiency. This test is often ordered along with or as a follow-up to a Protein S Activity test. Results of both tests can provide more information to determine the cause of the deficiency. A Protein S Deficiency Panel which measures both antigen and activity is also available.
