Method and device for platelets counting

摘要

Counting thrombocytes (T) contained in a blood sample (E), comprises: mixing the sample with fluorescent markers to bind specifically with thrombocytes, and an agent for inhibiting the activation of the thrombocytes; introducing the sample in a fluid chamber (FC) having at least one transparent side; capturing at least one digital image (IN) of the sample by fluorescence microscopy under fixed lighting; and counting thrombocytes present in each image by computing means for treating images (O). An independent claim is included for an apparatus for counting thrombocytes, comprising: a fluid chamber in which a blood sample is introduced, comprising a wall at least partially transparent and containing an agent for inhibiting the activation of thrombocytes and fluorescent markers bind specifically with the thrombocytes; a light source for carrying out stationary lighting of the sample for exciting the fluorescent markers; an optical system of fluorescence microscopy for capturing at least one fluorescence digital image of the sample; and computing means for processing images for counting thrombocytes automatically present in the or each fluorescence image.
