Antiphospholipid antibodies

Antiphospholipid syndrome is an autoimmune clotting condition associated with recurrent miscarriage and later pregnancy complications. Testing involves lupus anticoagulant and anticardiolipin antibodies, repeated at least 12 weeks apart to confirm. Where confirmed, treatment with aspirin and heparin in pregnancy is evidence based — unlike immune therapies offered for unexplained failure.

Also known as: APS, antiphospholipid syndrome, lupus anticoagulant
