  • Optical density values at 450 nm for aCL, aβ2GPI, aPS/PT, and aPT-A. All patients showed lupus anticoagulant, measured as prolongation of the clotting time.3,29 P2, P5, and P22 had levels of aPS/PT below the cutoff and were therefore omitted. Scoring system for the ELISA assays: + = from 0.25 to 0.5; ++ = from 0.5 to 1.0; +++ = from 1.0 to 2.0; ++++ = from 2.0 to maximum. White = Group A; Blue = Group B.
