Summary:
The research goal is to develop an algorithm for the processing of photo images of native blood samples to determine the concentration of erythrocytes, leukocytes and platelets without individual separate preparation of cell samples. Materials and Methods. The objects of investigation were the samples of the whole donated blood, diluted 400 times by saline. Special "photo templates", the effect of "highlighting" of leukocytes, which was detect by authors, and the resolution of platelets from leukocytes by the areas of their photo images were suggested for identification of the cells. Results. 80 photo images of native blood solutions were selected for computer processing, while the total number of cells counted was: erythrocytes — 4184, platelets — 292 and leukocytes — 84, total — 4560 blood cells. Comparison of the results achieved with ones obtained by "manual" account or by the device for formed elements counting Sysmex XT-400i gives satisfactory results. Conclusion. It is shown that the accuracy of counting of the native blood cells may be comparable with the accuracy of similar studies by means of smears. At the same time the proposed analysis of native blood simplifies greatly the samples preparation in comparison to smears, permits to move from the detection of blood cells ratios to the determination of their concentrations in the sample.
