ABSTRACT
The article describes a development related to the field of public health and molecular biology, in particular, medical diagnostics. We present the Isascreen-8 portable analyzer (Registration Certificate No. RZN 2022/17322, May 24, 2022) and its application for rapid diagnostics of a new coronavirus infection with the use of commercially available sets IsoAmp SARS-CoV-2 (Lytech Co. Ltd., Russia), and also our own development TB-IZATEST (Invention Application No. 2022133809, December 22, 2022) for diagnostics of tuberculosis pathogen. The approach proposed in this article can be used for rapid detection of genetic material (DNA/RNA) of Mycobacterium tuberculosis and SARS-CoV-2 in biological samples using the method of loop isothermal amplification in less than 20 minutes, and also as a universal platform for detection of genetic material of other pathogens in a biological sample. Using the proposed approach, various research tasks for epidemiological monitoring of tuberculosis and new coronavirus infection, qualitative and quantitative analysis of bacterial and viral load in samples, including evaluation of the effectiveness of the prescribed antibiotic therapy regimen, can be solved. The advantage is that this method can be used not only in diagnostic laboratories, but also in field laboratories in the most remote regions of Russia if the mandatory sanitary and epidemiological requirements are observed. With sufficient distribution, the proposed approach could help ensure epidemiological control of the prevalence of these socially significant infections.
