A short evaluation of a new haematological cell counter--the Cell-Dyn 3000--following a modified tentative NCCLS-procedure.
The proposed procedure offers a method of evaluation that is feasible, but still a very precise method, for the evaluation of electronic differential leukocyte counters. Following this abbreviated method, the classification of the leukocytes, from 5 x 20 unselected blood specimens, with a flow-cytometric analysis by the Sequoia Turner Cell-Dyn 3000, was compared with microscopic differential counts as the standard. With proven accuracy and good reproducibility, the Cell-Dyn 3000 is a good sieve for the selection of normal samples. The high sensitivity and fair specificity permits a reduction of the differential workload to about 30 percent of the normal workload.
