A review of platelet counting performance in the United States.
An interlaboratory comparison of platelet counting in clinical hematology laboratories in the United States is presented. Comparison of performance during the 1979 CAP platelet survey with performance in 1976 indicates a significant improvement in accuracy and interlaboratory precision. The calibration of instruments by clinical laboratories remains as a source of bias. Recommendations for calibration are presented.
