Antiphospholipid antibody testing and standardization.
The laboratory criteria that define patients with antiphospholipid syndrome (APS) include lupus anticoagulant (LAC), anticardiolipin antibodies and anti-β2 glycoprotein I antibodies (aβ2GPI). All assays show methodological shortcomings and the combination of the three tests, each with different sensitivity and specificity, and hence, differences in clinical utility make the laboratory diagnosis...
متن کاملStandardization of antiphospholipid antibody testing--historical perspectives and ongoing initiatives.
The measurement of antiphospholipid antibodies (aPL) has been an important aspect of antiphospholipid syndrome (APS) characterization since the disease was first described in the 1980s. Despite significant efforts geared toward the standardization of immunoassays that measure anticardiolipin antibodies and anti-β2-glycoprotein I spanning three decades, there are still reports of significant int...
متن کاملAntiphospholipid antibody testing: which are most useful for diagnosis?
Laboratory diagnosis of APS relies on the demonstration of a positive test for aPL. In clinical practice, the gold standard tests are those that detect beta2GPI-dependent aCL or LA. The question on the use of anti-beta2GPI asa routine diagnostic test remains unanswered, and testing for these antibodies should be only performed in very selected cases and not as an alternative to aCL or LA testin...
متن کاملANTIPHOSPHOLIPID ANTIBODY SYNDROME-A CASE OF AORTIC VALVE INSUFFICIENCY
A 31 year old woman was hospitalized for evaluation of aortic valve insufficiency and her present cardiac status. Clinical and paraclinical findings strongly suggested the presence of a collagen vascular inflammatory processprecisely, the antiphospholipid antibody syndrome (APS), with systemic lupus erythematosus as the underlying disease.
متن کاملAntiphospholipid antibody syndrome.
The 2006 International Consensus Statement on an Update of the Classification Criteria for Definite Antiphospholipid Syndrome has increased the time between the two laboratory studies required for diagnosis from 6 to 12 weeks. Antibody to beta2 glycoprotein 1 has been included as a criterion. Various non-criteria diagnostic clues such as livedo reticularis, heart valve disease, thrombocytopenia...
