MDC: Minimum detectable concentration

CV: Coefficient of Variation

Data in table from data in manufacturer’s manual for respective assays

Ranges provided for assay variation when %CV varied for testing of samples at low and high concentrations

For protein C, standard curve range was 12.5–150% activity and assay detection range was 5 % −200% activity.
