Covid-19 Testing

Diagnostic tests and Antibody tests are the two types of COVID-19 tests. Of the two, the former detects active COVID-19 infection using a nasal or nasopharyngeal swab, whereas the latter detects a past infection with the help of blood. Diagnostic tests are further divided into Antigen tests like Rapid and Molecular tests like the RT-PCR, NAAT, LAMP test. One should get tested for COVID-19 if he/she has symptoms of COVID-19 or had close contact with an infected person, or engaged in activities without social distancing.
