Strongly positive results for beta 2 glycoprotein 1 (beta 2 gp1) antibodies (>40 u/ml for igg and/or igm) are diagnostic criterion for antiphospholipid syndrome (aps). Centrifuge, separate and transfer the plasma or serum to a plastic vial. Reference range is standardized to the 99th percentile cutoff.
