Antiphospholipid Syndrome and EliA APS

Products are for professional/laboratory use only.

Antiphospholipid syndrome (APS) is an autoimmune disease which is characterized by the formation of various antibodies against phospholipids and a blood hypercoagulability. It may occur as an independent disease, or be associated with a range of rheumatic diseases such as SLE, SjS or RA.¹

At least one clinical and one laboratory diagnostic criteria must be present to establish the final diagnosis. A laboratory diagnostic classification criterion is regarded as met if two consecutive tests are positive conducted at least 12 weeks apart for lupus anticoagulant or antiphospholipid. Antibodies against cardiolipin (IgG/IgM) or β2-Glycoprotein I (IgG/IgM).²

Why choose EliA Cardiolipin and EliA β2-Glycoprotein I for APS diagnosis?

* Isolated elevation of IgA anti-cardiolipin and anti-β2-GPI antibodies can occur in APS patients³. The more markers / isotypes are found positive, the higher the probability for APS¹. Internal study shows that the test sensitivity and specificity of EliA Cardiolipin IgA are 21% and 98.5%, for EliA β2-Glycoprotein I IgA are 44% and 96.5%, respectively.
