Abstract：
:The lupus ratio (LR) test is a normalized ratio of the clotting times obtained with low and high phospholipid (PL) concentrations, where the test plasma is mixed 1:1 with normal pooled plasma (NP). As an integrated, automated, and computer-assisted assay, this principle has been applied to the dilute activated partial thromboplastin time (dAPTT) and dilute Russell viper venom time (dRVVT) test systems. In this study, we used recombinant thromboplastin to develop an automated LR test based on the dilute prothrombin time (dPT). Using plasma samples from a selected group of patients (N=92) with a well-defined lupus anticoagulant (LA) status, the dPT-based LR test showed fair agreement with the dAPTT-based LR test (kappa=.60, P<.001) and good agreement with the dRVVT-based LR test (kappa=.78, P<.001) regarding the classification of plasmas as LA-negative or -positive. Most discordant plasmas were low positive. Correlation between dPT- and dRVVT-positive LRs was only moderate (r(s)=.51, P=.002), and correlation between dPT- and dAPTT-positive LRs was nonsignificant (r(s)=.23, P=.18). Using dilutions of pooled LA-positive plasma, the dAPTT-based LR test appeared to be the most sensitive of the three tests. This study confirms the general validity of the LR principle and shows that the dPT-based LR test yields reproducible results. The low coefficients of variation (CV) of the LR assays, combined with a fairly low correlation among the three tests, support the assumption of antibody heterogeneity of LA-positive plasmas and the desirability of performing more than one test.
