The Protein S Antigen - Free test is a vital laboratory test used to measure the level of free protein S in the blood. Protein S is one of many factors that help to regulate blood clotting. A deficiency in Protein S can lead to an increased risk of abnormal blood clotting, which can result in conditions such as deep vein thrombosis and pulmonary embolism.

The Protein S Antigen - Free test is primarily used to evaluate individuals who have experienced abnormal blood clotting at a young age or have a family history of clotting disorders. Additionally, it can be used to monitor patients undergoing certain treatments that may affect protein S levels, such as oral contraceptives or hormone replacement therapy.
