About AIS Health Check
AIS Health Check provides private blood tests and health checks across the UK, working in partnership with Randox, a UKAS-accredited laboratory provider, to deliver accurate and reliable results. All test reports are reviewed by a qualified doctor, giving you clear medical insight you can trust.
Appointments are available at our Marylebone clinic, with most results delivered within 1-3 working days. There are no long NHS waiting times or GP referrals required, and we also offer private GP appointments for further discussion or follow-ups. We also have home tests available.
Online Private GP Appointments & Follow-Up Care
All test results include a doctor-written explanation, clearly outlining what your results mean and whether any values fall outside the normal range. If you have simple or minor questions about your results, these can be reviewed and answered by the doctor as part of this process.
We also offer online private GP appointments for individuals who would like medical advice, reassurance, or a more detailed discussion with doctors who take the time to understand your needs - whether or not you have completed a test with us.

I needed a hormone test and decided to try AIS Health Check - very glad I did. The appointment was quick, professional and nowhere near as long as my past NHS experiences. My results arrived faster than I expected as well which was great. Definitely recommend - Shannon Ford
