New Delhi: Omicron Variants (Omicron Variant) third wave of corona pandemic in india (Third Wave of Corona) has caused. This variant was identified by genome sequencing only. (Genome Sequencing) can happen through. But after collecting the sample, it takes 5 to 12 days for the results of genome sequencing to come. The reason for this is uncertainty, confusion and tension between patients and doctors. Initially, when there were only a few cases of Omicron infection in the country. In such a situation, those people who were found to be Kovid-19 positive were not allowed to go home till the negative report came. This was because their negative report of genome sequencing was delayed. However, the situation is still the same.
Epidemic and Public Health Specialist Dr Sunil Kumar explained the process of genome sequencing and explained why there is a delay in the arrival of this report. First the number of samples reaches the lab. The process of genome sequencing of about 300 samples can be started in a high capacity lab. The cost of each chip used in this process is 2.5 lakh rupees. Whether you test 10 samples or 300 samples, the cost of the chip will be 2.5 lakh only. Therefore, the process of genome sequencing is not started until 100 or 300 samples are collected.
The cycle threshold of the Kovid swab sample should be less than 25 for genome sequencing. Therefore not every sample can be tested with this method. At times, samples are not stored properly due to which those samples are disqualified. Most of the samples have low CT. Apart from this, due to the lack of kits for sequencing globally, the investigation is also affected.

So far, there are 2 labs for genome sequencing in the country in Karnataka and about 10 labs across India. The number of samples reaching these labs is increasing. Samples also come from neighboring states Andhra Pradesh, Tamil Nadu in Karnataka’s lab.
Dr Sunil Kumar said that there is a need to establish more such labs for genome sequencing in the country. These labs will be very useful even after Kovid. According to Dr Sunil Kumar, the number of infections, immune system, source of infection, re-infection and other reasons which are related to public health issue can be studied in people who have taken the vaccine through genome sequencing. Genome sequencing not only identifies variants, but genome sequencing can be of better help in epidemic-related surveillance.
At present, if a person wants to do genome sequencing on his own will, then he has to pay 10 to 20 thousand rupees. On the other hand, if a lab requires sufficient equipment for genome sequencing, then it costs Rs 1.5 crore.
