Precision and accuracy of the QC plasma samples.

<p>Shown are the precision and accuracy for each analyte at 3 levels in 3 batches (N = 6 per batch) and the inter batch statistics. The nominal concentration of QC2 was defined as the average measured value for the three validation batches. The nominal concentrations of QC3 and QC4 were the nominal concentration of QC2 + the respective spiking concentrations. The precision (coefficient of variation CV) and accuracy (%, where 100% is the actual value) are given for each of the individual batches and for the data-set as a whole.</p><p>Precision and accuracy of the QC plasma samples.
