Cardiolipin Antibody

To satisfy the laboratory criteria for APS there must be positive lupus anticoagulant (LA - refer to Haematology lab)) or medium or high titre anti cardiolipin or Beta 2 Glycoprotein on two occasions at least 12 weeks apart. This is because transient non-specific antibodies are common, especially associated with infection. The LA test is less sensitive but more reliable as it is more specific. Lupus anticoagulant test cannot be carried out on anticoagulated patients
