Clinical Info

This test can be used as an aid in the diagnosis of certain autoimmune thrombotic disorders, such as antiphospholipid syndrome (aPS). Antibodies to PS/PT correlate with the presence of lupus anticoagulants (LA), and this test may be useful in cases with difficult LA test interpretation. This assay also may assist in the determination of risk for thrombosis as well as obstetric complications in patients with antiphospholipid antibodies.
