Test Code ALUPO Lupus Anticoagulant Profile Interpretation


Specimen Required


 


Useful For

Interpretation of testing performed as part of a profile to confirme or exclude the presence of lupus anticoagulant (LAC), distinguishing LAC from specific coagulation factor inhibitors and nonspecific inhibitors

 

Interpretation of testing performed as part of a profile to investigatie a prolonged activated thromboplastin time, especially when combined with other coagulation studies

 

This test is not useful for the detection of antiphospholipid antibodies that do not affect coagulation tests. We recommend separate testing for serum phospholipid (cardiolipin) antibodies.

Clinical Information

Lupus anticoagulant (LAC) is an antibody to negatively charged phospholipid that interferes with phospholipid-dependent coagulation tests.

 

LAC is found in, but not limited to, patients with systemic lupus erythematosus; LAC is associated with other autoimmune disorders and collagen vascular disease and occurs in response to medications or certain infections (eg, respiratory tract infections in children) and in individuals with no obvious underlying disease.

 

LAC has been associated with arterial and venous thrombosis and fetal loss. Individuals with thrombocytopenia or factor II deficiency associated with LAC may be at risk for bleeding.

Reference Values

Only orderable as a reflex. For more information see ALUPP / Lupus Anticoagulant Profile, Plasma.

 

An interpretive report will be provided.

Interpretation

An interpretive report will be provided when testing is complete, noting a presence or absence of a lupus anticoagulant.

Cautions

No specific cautionary statements
