No-stress testing for COVID-19 travel
Negative COVID-19 tests are now a necessary part of any travel itinerary. Get your full programme of government approved, non-intrusive tests from Chronomics - keeping you safe every step of your journey, stress-free.
Testing for travel - what does it involve?
Reduce your quarantine period when you arrive back in England from countries not in a Travel Corridor. No invasive swab test and results within 24-36 hours of our lab receiving your sample.
Secure your internationally recognised certificate, allowing you to make your trip. Just take a simple saliva test in the few days before you’re due to fly out of the UK, and get quick results when you need them.
Both tests required by the Government after you arrive in the UK, without leaving your self-isolation address. Test yourself and get your results through one secure, easy-to-use online platform.
Get approval for your return to the UK without searching for specific Government-authorised testing locations abroad. Your results are delivered through our secure online platform.
