Insertion of discrimination reagent within 4 hours of Omicron… “We need to use it more”



Domestic companies first developed a genome amplification reagent that can identify a new mutated micron in up to 4 hours and started using it today (30th).

The quarantine authorities plan to monitor the spread of Omicron with this reagent, but it is pointed out that the number of test subjects must be significantly increased to prevent the spread.

Omicron mutation diagnosis genome amplification reagent developed in Korea.

With the development of this reagent, the time required for the Omicron discrimination test, which was a maximum of 5 days, was reduced to 3 to 4 hours.

If a diagnostic reagent is used in the obtained sample, it takes about 6 hours to confirm the corona virus, but if it takes another 3 to 4 hours, it is possible to know whether or not Omicron has been infected.

It is the first in the world to develop a diagnostic reagent that can discriminate both omicron mutations and conventional mutations.

The quarantine authorities plan to test all imported confirmed cases and up to 20% of local cases with this reagent.

Authorities explain that the purpose is to monitor the prevalence of mutations rather than to conduct a full test.

<김은진 / 중앙방역대책본부 검사분석팀장> “For the purpose of mutation monitoring, the local government’s Health and Environment Research Institute, the Korea Centers for Disease Control and Prevention, and regional response centers are conducting comprehensive nationwide monitoring of local outbreaks.”

However, the medical community points out that it is difficult to slow the epidemic only by using it for surveillance purposes, considering the rapid propagation power of Omicron, and the expansion of mutation testing is inevitable.

<이혁민 / 세브란스병원 진단검사의학과 교수> “The nature of avoiding the immunity of Omicron mutation, it is effective to use it in such a way as to see who the confirmed case of Omicron mutation is at the front line, and to strengthen the quarantine in case of close contact.”

Considering the transmission power of the Omicron mutation, the medical community expects it to become the dominant species in Korea as soon as next month, so it is time to think more about how to expand the test.
