Blood Chemistry In pharmacologic research a variety of clinical chemistry measurements are routinely monitored closely for evidence of side effects of the medication under study. Suppose typical blood-glucose levels are normally distributed, with mean = 90 mg/dL and standard deviation = 38 mg/dL. 5.31 If the normal range is 65−120 mg/dL, then what percentage of values will fall in the normal range? 5.32 In some studies only values at least 1.5 times as high as the upper limit of normal are identified as abnormal.
