Figure 1.
Effect of FV level on the APCsr determined with the Immunochrom APC Response test. The FV level was varied by mixing sample plasma with FV-deficient plasma in different proportions, and the APCsr was determined as described in “Materials and methods.” Each point is the average of 2 or more duplicate experiments, with error bars representing 1 standard error above and below the mean. Δ indicates normal plasma; ▪, FVR2-homozygous plasma; and •, FVLeiden-homozygous plasma.
