reference value

A range of expected measurements for a laboratory test. Findings outside the range may be abnormal or worth noting. Reference ranges may be determined or set in a number of ways: statistically, e.g., all values within two standard deviations of a mean data point; by consensus (all values thought by a panel of specialists to be acceptable or healthy); or pathologically (all values within the range are to be associated with good health; those outside the range are associated with the presence of a disease).
