LONDON – Lateral flow diagnostics specialist Mologic Ltd. has teamed up with Biosure Ltd., manufacturer of the only CE approved HIV home testing kit, to produce a COVID-19 antibody self-test. The companies are combining Mologic’s validated IgG antibody lateral flow strip with Biosure’s test kit, and say the product will be ready for mass production at the beginning of June.
The challenges to deploy diagnostic and surveillance testing for the COVID-19 pandemic will persist at least until a vaccine is ready if not well beyond that milestone. The state of COVID-19 testing as a regulated sector is a complex intersection of new and old technologies, questionable accuracy, availability hurdles, supply chain interruptions and problems with interpretation of results.
Researchers in Guangzhou, China, have developed a nanoparticle-based lateral flow immunoassay that quickly and accurately detects antibodies to the SARS-CoV-2 virus that causes COVID-19. The current test, which works in a similar manner to a pregnancy test, detects IgG antibodies in blood in less than 10 minutes. A proof-of-concept study appeared in Analytical Chemistry this week.
