Use of the Hemalog D Automated Leucocyte Differential Counter in the Diagnosis and Therapy of Leukaemia

Abstract
Of 46 adult patients with active leukemia whose white cells were examined using a Hemalog D automated differential leukocyte counter, 45 showed abnormalities indicative of their disease and the odd one out would not have been missed due to associated thrombocytopenia. Sequential studies while on chemotherapy allowed rapid and accurate neutrophil counts to be performed even in the presence of profound leukopenia and the re-emergence of blast cells in some cases was detected 2-3 wk earlier than by microscopy. The Hemalog D is reliable in the detection and can be useful in the follow-up of patients with leukemia.
