Table S3A: Freeze–thaw and autosampler stability in plasma.
A mixed lot of plasma was evaluated at three concentration levels (n = 3 per concentration level). The freeze–thaw stability values are normalized to values of freshly extracted samples. Samples that have been extracted and stored in the autosampler were compared to two freshly extracted calibration curves for the autosampler stability. Mean accuracies are shown. %CV: coefficient of variance.
