Mass testing for COVID-19 is not an easy feat. The current available methods of testing can produce false negative results and thus, aside from proper timing and correlation with clinical probability, multiple testing is frequently warranted. The US Food and Drug Administration (FDA) has recently approved saliva testing for COVID-19 as a more reliable and convenient means of testing.
Scientists are now looking to saliva testing for COVID-19
When it comes to combating COVID-19, mass testing is essential.
Mass testing can help identify infected individuals to treat and isolate them to prevent further spread of the virus.
However, the current methods of testing available are not perfect and have varying limitations in sensitivity. People who had been swabbed also shared that it was uncomfortable, since samples need to be scraped from deep inside the nose using a long probe.
Researchers, however, have found evidence that the viral load of a person with COVID-19 can be detected through saliva. RUCDR Infinite Biologics at Rutgers University in the US has developed a method of saliva testing for COVID-19. And the FDA has already approved its use.
How then is testing done using saliva?
All that a person needs to do is to spit into a container with a preservative liquid, which is then sent out for processing. Just like swab tests, saliva tests would also require a PCR machine to process the samples.
