Organization for laboratory diagnosis of SARS-COV-2 in the conditions of an anti-tuberculosis institution

Abstract

Introduction. In connection with the spread of a new coronavirus infection COVID-19 since 2020, measures have been taken in the city of Moscow to widely diagnose the causative agent of COVID-19. A laboratory PCR department was opened in the State Budgetary Healthcare Institution «MNPC for the fight against tuberculosis of the DZM», taking into account the available material and human resources. Purpose of the study: To generalize the experience of organizing the laboratory service of an anti-tuberculosis institution in the city of Moscow during the spread of a new coronavirus infection. Results. Human and material resources have made it possible to maintain the quality and availability of laboratory diagnostics of biological material from patients receiving treatment at the Moscow Regional Research and Practical Center for Combating Tuberculosis, DZM, during the COVID-19 pandemic. In the period 2020-2022 in total, 90,102 studies of biological material (smears) were carried out by RT-PCR in order to detect COVID-19 RNA. Starting from June 2020 to the present, the PCR department of the KDL Clinic 2 has been studying the direct detection of Covid-19 RNA in biological material using molecular genetic methods based on reverse transcription and polymerase chain reaction (RT-PCR) and the identification of specific immunoglobulin classes IgM and IgG to coronavirus antigens in blood serum (plasma) by the method of immunochemiluminescent analysis (ICLA) of both persons receiving treatment at the State Budgetary Institution of Healthcare Center for Combating Tuberculosis Moscow, and employees.
