Development and description of the "random duplicates" method of quality control for a hematology laboratory.
Calibration of laboratory apparatus is not sufficient to ensure accurate results. Application of the "random duplicates" method to the measurement of hemoglobin estimations and leukocyte counts by the Coulter Model S revealed unsuspected deficiencies in the laboratory operation. The resultant changes led to a significant improvement in the quality of work performed.
