Test Usage

Anticardiolipin antibodies are present in the antiphospholipid syndrome (arterial & venous thrombosis, recurrent foetal loss, thrombocytopaenia). The antiphospholipid syndrome can be primary or secondary to a CTD such as SLE. If antiphospholipid syndrome is suspected, a lupus anticoagulant screen should always be performed regardless of the cardiolipin result.

Clinical Advice

A definitive clinical diagnosis should not be based on the results of a single diagnostic method, but should only be made by the physician after all clinical and laboratory findings have been evaluated.
