Beta-2 Glycoprotein-1 antibodies - IgG and IgM


Suspected autoimmune arterial and / or venous thrombosis, thrombocytopenia, and repeated abortions. This is seen in primary antiphospholipid syndrome (APS) and systemic lupus erythematous with secondary anti-phospholipid syndrome (APS).


The analysis is performed by ELISA. Answers are given both in IgG and IgM antibodies.


The result is given as negative, borderline or positive with a value.


Elevated levels of antibodies against ?2-Glycoprotein-1 at two sampling occasions with at least 12 weeks interval is a marker for the anti-phospholipid syndrome (APS) that is characterized by recurrent arterial and/or venous thrombosis, and/or recurrent miscarriages. APS is often associated with SLE (secondary APS) but may also be seen without associated inflammatory disease (primary APS).

If suspicion of antiphospholipid syndrome (APS) remains despite negative results regarding the classical antiphospholipid associated antibodies (lupus anticoagulant (LA), IgG- and/or IgM-antibodies against beta2-Glycoprotein-1 and cardiolipin), IgA-antibodies against cardiolipin/ beta2-Glycoprotein-1 support the APS-diagnosis in isolated cases. In addition, antibodies against phosphatidylserine can be of value.
