(CSE: SONA), (OTCQB: SNANF) (the “Company”), a developer of rapid, point-of-care diagnostic tests, is pleased to announce that its rapid detection COVID-19 antigen test achieved a sensitivity of 84.6% and a specificity of 90.0% in a study across 99 collected clinical patient samples, which included 39 positive samples and 60 negative samples, as determined by RT-PCR testing.
