The introduction of automatic multichannel cell counters has increased the range of hematologic data available and also vastly increased reproducibility. In addition to their use in routine hematology, these features have been usefully applied in large-scale screening for thalassemias (1) and macrocytosis (2), and at times as a clue to the presence of cold agglutinins in high titers. Minor problems with the Coulter Model S1 have included a small positive error in hemoglobin measurement with high leukocyte counts, probably due to turbidity (3). On some machines, polycythemic blood read out with falsely low erythrocyte counts due to the lack of
