On Aug. 22, 2021, InBios announced that laboratory studies suggest its SCoV-2 Ag Detect Rapid Test detected the Delta variant (lineage B.1.617.2), which was responsible for a rapid rise of infections and deaths in the US and around the world.

Initial studies suggested that InBiosﾒ point-of-care antigen test will detect the Delta variant at rates similar to the USA-WA1-2020 isolate that was used to develop the assay.
