Diagnosis of leukocyte disorders with an automated haematology counter (Technicon H-1 analyser).

The differential leukocyte count is very important in the diagnosis of various leukocyte disorders. Newer automated haematology counters can now perform differential leukocyte count, thus reducing the dependence on experienced medical technologists. The Technicon H.1 analyser (Technicon Instruments Corp., New York, USA) can perform even more complicated tasks like flagging abnormal cells, generating cytograms based on cell size and cytochemistry. In this paper we report on the useful cellular characteristics of the various leukocyte disorders as measured by the Technicon H.1 analyser.
