title: [Laboratory diagnosis of antiphospholipid syndrome].
abstract: OBJECTIVE
  The antiphospholipid syndrome is a bioclinical entity defined by the occurrence of thromboses, and/or obstetrical complications in the persistent presence of antiphospholipid antibodies, i.e. lupus anticoagulant and/or anticardiolipin antibodies. This review focuses on the methods for antiphospholipid antibodies detection and their clinical usefulness.
  
  
  BACKGROUND
  Lupus anticoagulant is the strongest risk factor for thrombosis in antiphospholipid syndrome. Twenty years after its description, anticardiolipin ELISA, despite a still improvable standardization and its lack of specificity, is still required for sensitive diagnosis of antiphospholipid syndrome.
  
  
  CONCLUSIONS
  A better knowledge of the beta-2-glycoprotein-I role in the pathophysiology of antiphospholipid syndrome might lead to the development of new markers of thrombotic risk.
