Abstract
Recent CAP [College of American Pathologists] survey data have documented marked improvement in the reproducibility of hematologic tests [human]. The favorable outcome is attributable largely to the widespread use of automated whole-blood analyzers. Calibration variability detracts from this enhanced precision, and there are clear indications that improvement is necessary. Primary calibration methods for Hb, hematocrit and cell counting procedures are presented. The methods of applying these primary calibration methods to automated whole-blood analyzers are delineated. The use of both preserved reference blood and statistical control techniques for the identification of calibration loss is described.
