How accurate are the tests?

The Chronomics PCR tests use polymerase chain reaction methods in line with recommended UK, EU and USA government guidelines. 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%.
