Abstract
While lupus anticoagulant (LA), anticardiolipin antibodies (aCL), anti-β2 glycoprotein I (anti-β2GPI) antibodies represent the best available and the most widely used tests in the
investigation for antiphospholipid syndrome (APS), evidence gathered in recent years
indicates that other antiphospholipid antibodies (aPL) specificities may also play
a role in the syndrome. Several autoantibodies have been shown to be complexed with
phospholipids other than cardiolipin, or to some domains of β2GPI, or else directed to other proteins of the coagulation cascade, and these have
also been proposed to be of relevance to APS, and their diagnostic value and clinical
utility are the focus of current research.
