Clotting assay for Protein S (PS) anticoagulant activity in citrated plasma. PS is an APC cofactor; its functional activity is measured using Protein S-deficient plasma substrate. CE-IVD.

PS deficiency — congenital or acquired — is associated with elevated venous thromboembolism risk. Functional assay detects Type I and Type III deficiencies (which have reduced PS activity).

• Clotting method measuring functional PS anticoagulant activity
