Even before starting treatment, one must first identify whether a person is really suffering from the deadly virus. To do this, we have a number of techniques available, including a molecular RT PCR test, a rapid antigen test, or a COVID-19 test at home.
RT PCR is said to be the most accurate form of covid test, where swabs are taken from a person’s throat or nose or both. Sawab samples are then sent to the laboratory, where scientists look for the genetic material of the RNA or virus, which may present the most accurate results.

But it can take a long time to show PCR test results, when quick tests come in handy. They are instantaneous in providing results because the technology it uses identifies only proteins in the virus strain instead of the entire virus RNA. This is also one of the reasons why quick test results can be false negative.
That said, although RT PCR and rapid testing have some advantages and disadvantages, experts have come up with another diagnostic tool that can help detect COVID-19. Read on to find out what it is.
