Over the past 20 years, non-criteria antiphospholipid antibodies (aPL) directed to other proteins of the coagulation cascade (i.e. prothrombin and\/or phosphatidylserine\u2013prothrombin complex) or to some domains of \u03b22GPI have been proposed. This task force concentrated and reviewed the literature on data including aPS\/PT, antibodies to domain 4\/5 of \u03b22GPI and the newly described antibodies to protein\/HLA-DR complex. In addition, we discussed testing of LA in the \u2018new\u2019 oral anticoagulants\u2019 era and the value of triple positivity in the risk assessment of aPL.
