Definitions related to normal range:
  • In medicine, a set of values that a doctor uses to interpret a patient's test results. The reference range for a given test is based on test results for 95% of the healthy population. Sometimes patients whose test results are outside of the reference range may be healthy, and some patients whose test results are within the reference range may have a health problem. The reference range for a test may be different for different groups of people (for example, men and women).
