METHOD OF DETERMINING PLATELET RESISTANCE TO ACETYLSALICYLIC ACID

FIELD: chemistry.SUBSTANCE: invention relates to method of determining platelet resistance to acetylsalicylic acid (ASA) by impedance analysis of aggregation function of platelets in vivo, in which aggregation activity is analyses after incubation of biological material sample with ASA with application of aggregation inducer, and aggregation of platelets is induced by collagen in optimal concentration 2 mg/ml, and simultaneously with measurement of impedance determination of dynamics of platelet granules release is performed by luminescent method, where before carrying out aggregation samples are calibrated by means of adenosine triphosphate (ATP) standard, value of aggregation amplitude are determined in Ohms by obtained aggregatograms and obtained values are given points: values ?6 correspond to 0 points, values 7-9 correspond to 1 point, values 10-12 correspond to 2 points, values >12 correspond to 3 points; after that, intensity of ATP release from platelet granules is determined in nmoles and obtained values are given points: values 12 соответствуют 3 баллам; за
