Additional antibodies directed against phospholipid/phospholipid-protein complexes for which testing may be useful in selected cases (seronegative APS, because they are not part of the 2006 consensus criteria) include the following [19, 20, 9] :

  • IgA aCL
  • IgA beta-2 glycoprotein I
  • Anti-phosphatidylserine antibodies
  • Anti-phosphatidylethanolamine antibodies
  • Anti-prothrombin antibodies
  • Antibodies against the phosphatidylserine-prothrombin complex
