The Chronomics saliva test and the Chronomics oronasal swab uses polymerase chain reaction (PCR) methods in line with recommended UK, EU and USA government guidance.

This is the gold standard of testing currently available, with a specificity greater than 99.99% and a sensitivity greater than 97% - exceeding current international minimum standards. 

Our ‘test to return’ antigen (rapid flow) tests have a specificity of 99.6% and a sensitivity of 95.5%. 

You should double-check with the airline you’re using and the country you’re travelling to, as requirements can differ, although our tests are very likely to be accepted by all.
