There are at least two strategies to establish COVID-19.
- 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).
- A CRISPR-based detection. Using a protocol called SHERLOCK, which identifies the two SRS-Cov2 genes a specific readout for viral RNA is generated.
- 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.
