A complete blood count (CBC) screening is a routine exam requested by most physicians for healthy adults. Currently, the results of CBC tests are analyzed using a one-size-fits-all reference interval, but a new study suggests that this approach can lead to overlooked deviations in health. In a retrospective analysis, researchers show that these reference intervals, or setpoints, are unique to each patient. The study revealed that one healthy patient's CBC setpoints can be distinguishable from 98 percent of other healthy adults.
