Abstract:

White blood cell WBC counts obtained using a Technicon H6000 in a large occupational health program were compared with counts obtained on identical samples using a Counter Counter Model ZBI. To assure quality control and to assess the comparability of results obtained on the two machines, a 25 systematic sample N 586 of analyses performed on the Technicon were independently and blindly performed on the Coulter Counter. The Pearson product-moment-correlation between WBC counts from the two machines was r .94 p less than or .0001. The mean WBC count was 6,664 cellscu.mm for the Technicon and 6,790 cellscu.mm for the Coulter Counter. The estimated prevalence of leukopenia WBC counts less than or 4,500 cellscu.mm was 10.6 using the Technicon and 9.7 using the Coulter Counter. The results demonstrate that the two machines provide results which can be directly compared without corrections.
