LT Biotech Ltd. antigen rapid test detects fragments of proteins of the SARS-CoV-2 virus from a human nasal swab sample.

Tests require a swab from the back of nose or throat as a sample and it works by mixing the sample with a solution that unleashes specific viral proteins. That combination is then applied to a paper strip that contains a bespoke antibody optimized to bind these proteins if they are present. Test result is reflected as a band on the paper strip.

The process doesn’t require a lab, and can be done in home conditions in up to 15 minutes.
