Recovery is estimated as a percentage value using (measured value of the analyte/target concentration) x 100. When the target value is the same as the measured value, the recovery is estimated to be 100%. If the measured value exceeds or is below the target concentration, the values are appropriately measured as greater or less than 100% recovery. A total of 250 data points were measured over a 6 months period.
