title: Antiphospholipid antibodies: method of detection.
abstract: Antiphospholipid antibody, measured by enzyme-linked immunosorbent assay (ELISA) or by radioimmunoassay, and the lupus anticoagulant represent similar but different tests. The ELISA is now well standardized. It is at least partly, and possibly primarily, dependent on the presence of a cofactor, beta 2-glycoprotein I. Tests for both antiphospholipid antibody by ELISA and lupus anticoagulant should be performed in patients suspected of having this syndrome.
