The second wave of Coronavirus took over the country like a storm, and testing has once again become highly essential to curbing the spread of the virus. However, a lot of discrepancies are being observed in testing, especially in Telangana. Experts say that this is because a lot of people are mostly turning out to be asymptomatic.
For example, if a person tests negative on an RT-PCR test, an infection is being found on an MRI scan. It is also being said that these discrepancies are because sample collection protocols are not being followed properly by those collecting the samples and that the highest number of discrepancies are being found from the samples that are being collected from homes.
Experts also say that sometimes RT-PCR tests come out negative because the infection will have moved to the stomach and because the sample taken at the throat wouldn't be helpful. Experts have also explained the various stages. The viremia stage lasts for five days to seven days, the early pulmonary stage lasts for five days, and the late pulmonary stage begins from the 12th day and could continue for two or three weeks.
Experts say that the best time to get yourself tested during the Viremia stage would give out the best results, as the infection moves to the stomach after that.
