Our Laboratory

The Preventx in-house laboratory is a UKAS ISO 15189 accredited medical laboratory (no. 7568) and adheres to a strict quality system.

We only process our own tests, from our own sampling kits and with a focus on sexual health. We don’t process tests for anyone else, so no other work is more important or higher priority.

Preventx is the only digital sexual health service with its own in-house laboratory, and we have developed and evolved our processes specifically to test the small samples that are produced through self-sampling. For example, we can carry out up to six tests on a single finger-prick blood sample, plus confirmatory testing and assays such as quantitative RPR.
