Who are HALO™?

The HALO team includes world-class science, technology and logistics experts who want to help find solutions to the COVID-19 pandemic. HALO is an independent, self-funded UK startup that was conceived, designed and built to do consumer-friendly healthcare testing at scale. It’s not a repurposed lab, app or pharmacy.

HALO invested in our own gene sequencing RT-PCR lab facility based in the Imperial College campus at White City, London. We are an approved ABTA testing partner and our tests are accepted worldwide (customers should check local rules). HALO is the only test service to partner with UCL and the Francis Crick Institute to detect and protect against new variants.

Rapid, accurate and affordable testing

PCR is by far the most accurate, sensitive and specific test for Covid-19. Most PCR tests are swab-based: The Lancet says saliva sampling is actually better, as well as simpler and less painful. We use non-invasive, saliva-based testing, without the need for nose and throat swabs, to provide accurate results, simply and without discomfort. Just spit in a tube, scan it with the HALO app and you’re done. The Sunday Times calls us “the best spit test on the market”. With almost 100% accuracy you can rely upon our simple and affordable tests to give you the confidence to get moving again.
