APPLICATION OF QUANTITATIVE METHODS FOR STUDYING BLOOD AND BODY EXCRETION TRACKS ON MATERIAL EVIDENCE IN THE PERFORMANCE OF FORENSIC BIOLOGICAL EXAMINATIONS
The publication presents the generalized results of experimental studies of blood, sperm and saliva samples produced using modern highly sensitive methods: quantitative enzyme-linked immunosorbent assay, colorimetric and kinetic methods. The stability and activity of total IgG samples, a-amylase samples, total PSA samples in aqueous extracts were studied, the possibilities of evaluating the intralaboratory quality control of investigations were shown. Based on the performed analysis of the special literature of domestic and foreign authors regarding the use of high-quality methods for studying material evidence in practice, an improved version of the scheme for their application in the production of forensic biological examinations of human blood and excreta (sperm and saliva) was proposed.
