Correlation between rivaroxaban plasma level and functional LA test results. Measurement results of (a) dRVVT screen, (b) dRVVT confirm, (c) dRVVT ratio, (d) LA-sensitive aPTT, (e) aPTT, and (f) ratio of LA-sensitive aPTT/aPTT in n = 320 patients under anticoagulant treatment with rivaroxaban are shown. The intersected line indicates the upper reference limit of the functional LA tests of 1.2. The solid line indicates the Pearson correlation with the rivaroxaban plasma level, r indicates the correlation coefficient. LAS aPTT, Lupus anticoagulant sensitive aPTT; dRVVT, dilute Russell viper venom time.
