Forensic medical definition of blood menstructural origin for its characteristic components

The aim of the work was to develop new forensic medical criteria for establishing the menstrual origin of blood by its specific and biochemical parameters. The standard method for establishing the menstrual origin of the blood, the author’s (organoleptic and sensory) methods for the determination of trimethylamine, the methods of chromatographic and gas chromatographic studies, the method of comparative analysis and statistical processing of the obtained results were used in the work. As a result, we first discovered that the detection of diagnostic values of such components of blood such as: trimethylamine (TMA); saturated fatty acids (NLCs), unsaturated fatty acids (NNHCs) and polyunsaturated fatty acids (PUFAs); certain content of linoleic and linolenic acids, arachidonic acid, and also PG F2α prostaglandins, indicate menstrual blood origin. For the first time, forensic medical practice has developed its own algorithm for establishing the menstrual origin of blood, which is based on the identification of substances that are components of the menstrual blood, and allows to significantly objectify the process of diagnosing the presence of blood menstrual origin, and a diagnostic system for the establishment of menstrual origin blood
