PortNAT is the world's first CE-certified portable nucleic acid test, which enables standard nucleic acid sampling and automatic reading and diagnosis at home. The product consists of a reusable incubation base and replaceable consumables, allowing users to obtain accurate test results rapidly through simple operations without professional training. PortNAT ensures the accuracy of each result with its ultra-high sensitivity and specificity. Based on this platform, Ustar is expected to develop a plurality of nucleic acid test products in the future, which, for example, can be used for nucleic acid tests and discriminatory identification of Influenza A, Influenza B, COVID-19 viruses and COVID-19 mutant strains.
