How COVID-19 is tested in the laboratory?

There are at least two strategies to establish COVID-19.

1. A PCR test which relies on the amplification of a fragment of the viral RNA and detection of the signal. Most current tests available use this mechanism. This test is done by swabbing the infected region (respiratory system).
2. A CRISPR-based detection. Using a protocol called SHERLOCK, which identifies the two SRS-Cov2 genes a specific readout for viral RNA is generated.
3. An antibody test which relies on the detection of antibodies that are produced in response to the viral particles in the blood. This test needs a blood draw.
