Once the results were obtained, the patient results were compared to the reference ranges, and as well, the QC results were compared to the reference ranges to insure that the results are accurate and acceptable and to prevent erroneous patient results from being reported. For, if the patient results fall outside of the reference ranges, it can be concluded that abnormalities are in the patient sample. When evaluating the QC results, it was found that both QC 1 and QC 3 presented problems for there was too great a variability in the results; for, both values indicated that the results were unacceptable for one, QC 3, was outside of three standard deviations on the mean which is a violation of the 13sWestgard rule which corresponds to a Levy-Jennings chart having values set plus or minus three standard deviations from the mean while the other, QC 1, was outside of two standard deviations of the mean which is a violation of the 12s rule which corresponds to a Levy Jennings chart having a value plus or minus two standard deviations form the mean. When evaluating QC 1 results, the mean value of the reference range was 0.85 mg/dl with one standard deviation being 0.1 mg/dl and the acceptable range between 0.65 mg/dl and 0.105 mg/dl. The QC 1 value was 0.638 mg/dl which is outside of two standard deviations. When evaluating the QC 3 results, the mean value of the reference range was 6.35 mg/dl with one standard deviation being 0.7 mg/dl and the acceptable range between 4.95 mg/dl and 7.75
