Genetic and antigenic tests

The SARS-CoV-2 coronavirus belongs to the group of RNA viruses – pathogens responsible for diseases of the upper respiratory system, including colds. The consequence of infection with the virus is a wide range of symptoms, including fever, cough, difficulty breathing and fatigue. One of the most severe consequences of infection with SARS-CoV-2 virus is severe acute respiratory syndrome. This is especially true of the elderly and people with significant immunodeficiencies. In late 2019, the SARS-CoV-2 virus triggered a wave of infections that spread rapidly around the world and was declared a pandemic in March 2020 by the WHO World Health Organization.

The SARS-CoV-2 virus is transmitted mainly by airborne droplets through coughing, sneezing or close contact with infected people. The estimated median incubation time is approximately 5.1 days, and the expected duration of symptoms is 12 days from infection.

Diagnosis
of SARS Cov-2 infections

The diagnosis of SARS-CoV-2 infections is based on the detection of viral RNA by reverse transcription polymerase chain reaction (RT-PCR – direct diagnosis) or viral protein by serological tests (ELISA – indirect diagnosis) in the material taken from the upper respiratory tract (nasopharyngeal swab) or oral cavity) or from the lower respiratory tract (bronchoalveolar lavage, tracheal discharge, sputum). According to the recommendations of the WHO World Health Organization, the most important factor in inhibiting the spread of SARS-CoV-2 is the detection of infection at its initial stage, therefore, tests based on the PCR method should be used, which detect the genetic material of the virus. RT-PCR enables the detection of the pathogen even in subclinical or asymptomatic courses already a few days after contact with the virus and up to 14 after the onset of possible symptoms.

COVID-19 diagnostics also includes serological tests for the differential detection of antibodies of different classes of immunoglobulins and against different SARS-CoV-2 antigens. Antibody testing allows confirmation of viral infection in patients with typical symptoms, including acute symptoms, and in suspected asymptomatic cases. Serological testing is also helpful in monitoring and controlling epidemics.
