How our testing works

Take our self-assessment or fill in our online booking form.

Simply share your symptoms, health history and goals on our online questionnaire - and we’ll analyse your data to give you our tailored recommendations.

Order your at-home testing kit or book an appointment at one of our clinics.

Depending on the test, you’ll receive your at-home kit within 2-3 days, or you’ll be sent a link to book an appointment at your nearest clinic.
