• A normal test result is typically differentiated from an abnormal result by identifying those values that fall within (normal) and outside (abnormal) the 95% confidence interval for that test, after the test is evaluated in healthy individuals from the intended population. This approach acknowledges that 5% of a normal population will have an abnormal test result and some individuals with a normal test result will have the disease the test is designed to identify. Such trade-offs are common in the practice of medicine.
