Who are Chronomics?

Founded in 2017 as an epigenetics company, we’ve got lots of experience analysing people’s biological samples to give them actionable information about their health. Now, we’re using that expertise to help in the fight against COVID-19.

Our range of COVID-19 testing kits include rapid lateral flow tests, antibody tests and one of the world’s first saliva tests for coronavirus. They’re fast, easily performed at home and our saliva PCR tests are as highly accurate as others that use uncomfortable swabs. It’s also simple to register online with pre-paid priority delivery included, so your results will be with you in plenty of time for travelling.

Our tests use cutting-edge, entirely safe technology that has been scientifically validated in the UK, the EU, the US and by the World Health Organisation (WHO).
