Patterson Blank 0.00 0.00 Patient 0.505 174.740 Standard 0.578 200 QC Level 1 1.006 348.097 QC Level 3 0.558 193.08 Calculations: Blank: 0.00/0.578 x 200 mg/dl = 0.00 mg/dl Patient: 0.505/0.578 x 200 mg/dl = 174.740 mg/dl Standard: 0.578/0.578 x 200 mg/dl = 200 mg/dl QC Level 1: 1.006/0.578 x 200 mg/dl = 348.097 mg/dl QC Level 3: 0.558/0.578 x 200 mg/dl = 193.08 mg/dl Discussion: 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 they were both outside of three standard deviations on the mean which is a violation of the 1 3s Westgard rule which corresponds to a Levy-Jennings chart having values set plus or minus three standard deviations from the mean. When evaluating QC 1 results, the mean value of the reference range was 230 mg/dl with one standard deviation being 25 mg/dl and the acceptable range between 180 mg/dl and 280 mg/dl. The QC 1 value was 348.097 mg/dl which is well beyond three standard deviations. When evaluating the QC 3 results, the mean value of the reference range was 100 mg/dl with one standard deviation being 10 mg/dl and the acceptable range between 80 mg/dl and 120 mg/dl.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
