Two tests are ordinarily done before pronouncing a person as coronavirus-positive.

In the first stage, a nasal or throat swab is tested for the presence of the virus — to detect the “viral load”. Strands of genetic material (for the novel coronavirus it is RNA) are isolated through a process called Polymerase Chain Reaction (PCR). This test can happen at any of the labs in the chart alongside.

In the next stage, the identity of the virus is confirmed through genome sequencing. This test is available only at the National Institute of Virology, Pune. The test was developed almost overnight after the identity of the novel coronavirus was revealed in December last year.
