Idet drotrecogin alfa (aktiveret) kan påvirke APTT- analyser, kan drotrecogin alfa (aktiveret) i en plasmaprøve interferere med ettrins koagulationsanalyser baseret på APTT (såsom faktor VIII, IX, og XI analyser).
Because drotrecogin alfa (activated) may affect the APTT assays, drotrecogin alfa (activated) present in plasma samples may interfere with one-stage coagulation assays based on the APTT (such as factor VIII, IX, and XI assays).
