The results are compared from the platelet count in blood via chamber method with phase contrast and via electronic method with "Thrombocounter C". The reproducibility was studied in a series in the low, referent and high region. The electronic-automatic method gives a better reproducibility than the chamber method in all three regions. The poorest is the reproducibility in the low region where VC of both methods were the closest. The results from the two methods are in a high positive correlation (r = 0.9145, n = 61), the arithmetical mean from the electronic method being insignificantly higher than the mean of the chamber method, p greater than 0.05. In the low region, with platelets under 80 X 10(9)/l, the reliability of the electronic-automatic method is decreased. The results from the chamber and electronic-automatic method have a normal distribution. The electronic-automatic method is several times faster and less tiresome than the chamber one.

D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
