Description

Aids in characterization of Antithrombin deficiency (AT, previously referred to as Antithrombin III) which is associated with increased thrombotic risk. Type I deficiency is characterized by reduction in activity and antigen levels simultaneously. With type II deficiency, activity levels are lower in comparison to the antigen levels (dysfunctional protein). Acquired deficiency, more common than inherited defects, can occur due to: liver disease, nephrotic syndrome, heparin therapy, disseminated intravascular coagulation (DIC), sepsis, and L-asparaginase chemotherapy.

Note: Target-specific anticoagulant therapy (anti-Xa medications, direct thrombin inhibitors) may cause false positive results for Lupus anticoagulant testing but do not impact the Cardiolipin, B2GPI and Phosphatidylserine-Prothrombin antibody testing.
