Understanding Antiphospholipid Syndrome
Antiphospholipid syndrome is characterized by the immune system producing antibodies that can lead to the formation of blood clots in arteries and veins. The main antibodies involved include lupus anticoagulant, anticardiolipin antibodies, and antibeta-2 glycoprotein-1 antibodies. Accurate testing for this syndrome requires a combination of these tests, typically conducted as reflexive panels to ensure no relevant antibodies are overlooked. The testing for lupus anticoagulant uses uncalibrated clot-based assays, while anticardiolipin and antibeta-2 tests utilize calibrated solid-phase immunological methods.
