A quality control analyst named Niana noticed a deviation for the month of February in the Levey Jennings chart of the analyte, HDL. She noticed several deviations which include the following: I. From February 8-11, the high control measurements were in the -2SD control limit II. On February 19, the low control measurement was at -2SD, but on the 20th of February, the low control measurement was at +2SD III. From February 10 to 19 the normal control measurements were in the +1SD control limit IV. On February 27, the high control measurement went beyond the +2SD 1. Which of Niana's findings were consistent with RANDOM ERROR? A. I, II, III, IV B. I, II, III C. I and III only D. II and IV only 2. Which of Niana's findings were consistent with SYSTEMATIC ERROR? A. I, II, III, IV B. I, II, III C. I and III only D. II and IV only 3. What will be your course of action if a run similar to the February 27 findings occurs? A. Reject run and investigate on systematic errors B. Accept run and inspect data by other control rules C. Reject run and investigate on random errors D. Repeat run and if the result is the same, report it. 4. What is being indicated by the control measurement on February 27? A. is a "warning rule to not accept the run. B. When followed by another run on the same control limit, it is indicative of a systematic error. C. It is a rejection rule primarily sensitive to random error D. It is a rejection rule primarily sensitive to systematic error
