Abstract. An optical-electronic system is designed to detect tiny blood clots directly in test tubes with blood samples prior to processing the samples with hematology analyzer or cytometer. The analysis is carried out directly through the test tube wall, in a thin layer of the blood flowing down the inner tube wall. Relying on results of experimental studies, it is inferred that a conclusion on the presence of tiny blood clots in a blood sample can be made based on the blood cells mobility, as well as on the structure of conglomerates of cells and the presence of platelets.
Keywords: optical-electronic system, blood analysis, tiny clot, blood cell, image processing
