Seegene Inc. unveiled another series of diagnostic test that detects the ever-changing COVID-19 variant landscape. The Novaplex™ SARS-CoV-2 Variants VII assay addresses Omicron and its stealth version, as well as other variants. The company believes the new PCR test will be effective in helping governments and health authorities to fight current variants. Immediately after the World Health Organization (WHO) announced a discovery of the Omicron variant, the company implemented its AI-based in-silico system to conclude this development within a week. In a single tube, the new RT-PCR test targets a total of five analytes including the RdRP gene, which confirms positive COVID-19 cases, and three key Omicron S-gene mutations: E484A, N501Y, HV69/70 deletion. And it also targets Endo IC, which serves as a control to verify specimen validity. The assay was validated using variable nucleic acid of COVID-19 samples including Alpha, Beta, Gamma, Delta, and Omicron cases. This latest test can differentiate between the Omicron variant and its 'stealth' version. The newly emerging stealth version lacks certain features (HV69/70 deletion) that are being targeted by other PCR tests to identify the Omicron variant. Company's proprietary mTOCE technology makes it possible to target multiple genetic mutations in S-gene so this test can accurately distinguish the new Stealth variant from standard Omicron.
