Explain how a reference interval is determined
What will be an ideal response?
Answer: A reference interval for a given geographical region is determined by calculating the mean for a group of "normal healthy" individuals. Conditions that must be considered include physiologic differences in a given population as well as the geographic area. Once the mean has been determined, a calculation to determine the standard deviation must be performed. The range is calculated by taking the mean and 2 standard deviations above and below the mean value.
