文摘

Detection of anti-phospholipid (aPL) antibodies for state-of-the art diagnosis of antiphospholipid syndrome(APS) still remains a laboratory challenge due to the great diversity of aPL antibodies and their relevance with regard to the diagnostic criteria. According to the recently revised classification criteria for APS, several enzyme-linked immunosorbent assays (ELISAs) should be performed simultaneously in routine laboratories for the detection of aPL antibodies. Therefore, new approaches to aPL profiling have been proposed recently to provide information regarding diagnosis and eventually outcome in APS patients. Multiplex analysis could meet the increasing demand for cost-efficient detection and profiling of aPL antibodies. Multi-line immunodot assays or bead-based multiplex techniques candidate as alternatives to assess several aPL antibodies simultaneously employing different solid-phases for bound/free separation of reactants. Particularly, multi-line immunodot assays present an alternative to ELISA for aPL antibody detection and profiling in APS patients. The use of hydrophobic membranes as solid-surface by this technique appears to offer a distinct solid-phase reaction environment for the assessment of aPL antibodies. This article reviews novel developments in the field of laboratory diagnostics of APS with special emphasis on multiplex assays.
