Ezplex�® SARS-CoV-2 G Kit, developed by SML Genetree, is a product that has received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA). This is an in vitro diagnostic test that qualitatively detects the nucleic acids of SARS-CoV-2 (RdRp and N genes) in sputum to aid in emergency screening for COVID-19. This product can be used for a large amount of screening tests because it can perform a pooling test, unlike the products that the existing domestic companies have approved for emergency use by the FDA. For the combined test, samples are collected in units of 5 people and tested. If positive, individual tests are performed. In the case of a negative test, all tests are performed in a negative way. In particular, since a large number of samples are tested at once, the test is only possible with high sensitivity and specificity compared to existing diagnostic kits. According to the FDA, it was confirmed that 100% agreement was achieved in the result comparison test of individual and collective tests, and it was the 20th in the world and the first Korean company to pass the test. Excellent clinical performance was demonstrated by confirming high sensitivity and specificity through clinical evaluation, and stability was confirmed for 12 months through long-term storage tests. In January 2021, it was officially approved by the Korean Ministry of Food and Drug Safety (MFDS).
