[The use of laser diffraction spectroscopy for measuring the size distribution of human thrombocytes].

The proposed procedure for obtaining the distribution of human platelets by their sizes by using laser diffraction, followed by computer processing of the results permits studies by defining quantitative parameters, such as the pattern of distribution, the count of platelet populations and the variations in platelet counts in the populations. This procedure may be used to examine the functional status of cells in health and in disease.
