Which test will show Omicron variant infection or not?

The new variant of the corona virus, Omicron, has also hit India, frightening everyone. Luv Agarwal, Joint Secretary of the Ministry of Health, said during a news conference last Thursday that "In Karnataka, two cases of omicrons have been verified. In reality, the infected people are 66 and 46 years old, respectively. The World Health Organization, on the other hand, claims that "Omicron poses a significant threat to the whole world. According to initial report, omicrons have a great tendency to infect a person and can also have a significant impact on the immune system. At the same time, we'll tell you the test you may do to find out if this omicron variety exists.

"The good thing with Omicron is that it may be recognised by some RT-PCR testing," according to the World Health Organization. "This can help identify and prevent further spread," he added. To detect many more variations, genetic sequences must be used. Some scientists, on the other hand, argue that "this is not such a direct instance." The majority of RTPCR tests can't tell the difference between omicron and other variants. "RT-PCR tests only reveal if a person is infected with corona, not variations," experts added. A genome sequencing study is required in this scenario. However, genome sequencing is not possible for all contaminated samples. This is a time-consuming, complicated, and costly process. The existence of viruses in the body is shown by RTCR testing.'

It's also been reported that while most public and commercial lab tests can detect SARS Cov-2 infection, it's impossible to know which form of the virus an infected individual has. According to experts, "these tests seek for portions of the virus that don't change significantly." The variation is chosen based on the mutation difference. This variation in omicrons is connected to spike protein mutations, a component of the virus that changes often to protect itself against drugs and disease-resistant cells. That is why checking is tough. 'Most tests will reveal that the so-and-so has a corona infection, but he will not state whether or not the so-and-so has the omicron variety.'

"For this, the doctor will have to send your sample to a lab that can look for genetic signatures like omicrons with the help of genetic sequences," scientists say. '
