S Witte · PubMed · 1978
This report is based on own practical experiences with the Hematrak during seven months of daily use in the hematologic routine in a general hospital. We describe briefly the operation of the instrument. The importance of the preparation of the slides is stressed. In this respect a device for automatic smear preparation is mentioned. To test the reliability of the instrument the differential counts of the instrument were compared with manual results and regression values calculated. The reproducibility was checked and calculated. The next point of interest was the number and kind of cells determined as "suspect" by the instrument. Finally we tested how pathologic cells were detected and determined by the instrument.
