Different diagnostic method of COVID-19

 

As winter moves in, COVID-19 cases, hospitalizations and the number of deaths across the world are incredibly rising. In all its various methods, testing is and will be a mainstay for the foreseeable future. However, it is critical to choose the method of testing since the best solution may be not the same during the whole progression of COVID-19.

 

So far there are three main types of diagnostic tests of this pademic: molecular assays (PCR tests) that rely on nucleic acid amplification tests (NAAT) for detection of genetic sequences of the SARS-CoV-2, the virus that causes COVID-19 disease; immunoassays to test the antigen (antigen tests) or to test the antibody (antibody tests) that can be used to detect the presence of antigens by targeting the viral envelope or to detect antibodies that have been produced against the virus during the immune response.

In addtion to different concentration of materials to be dectected based on the progression of the disease, there are other concerns that may affect the healthworkers’ decisions of diagnostic strategy.
