When a new type of test is developed, the manufacturer effectively accredits it themselves. Reputable companies will then run trials to show how good the test is compared with other tests – how sensitive and how specific – and will publish the details of the test and the detail of the trials so that laboratories can decide whether they want to use the test.

The published conclusions are only as good (or as bad!) as the trials. If you have queries about a specific test, then contact us.
