Thrombotic Risk Assessment
Use
The Thrombotic Risk Assessment is a coagulation profile designed to detect both acquired and congenital causes of thrombophilia, providing a broad evaluation of thrombotic risk. The acquired component includes anticardiolipin antibodies (IgA, IgG, IgM), antiphosphatidylserine antibodies (IgG, IgM), β2-glycoprotein 1 antibodies (IgA, IgG, IgM), lupus anticoagulant reflex, and thrombin mixing study. The congenital component assesses activated protein C resistance (APCR), antithrombin activity, protein C functional activity, and free protein S level. Results support risk assessment and clinical decision-making for patients with personal or family history of venous thromboembolism or thrombophilia risk factors.
Special Instructions
If the patient’s hematocrit exceeds 55%, the volume of citrate in the collection tube must be adjusted. Refer to Coagulation Collection Procedures for guidance.
