Who this is for
Calibre members who have experienced
Dr Reinholds approach
Calibre gave me a much clearer understanding of my health than any standard check-up I've had before. Instead of just receiving test results, everything was explained in context with practical, personalized recommendations that were easy to follow.
Maya
Really smooth experience so far - loved the initial assessment experience including the in-depth chat with my dedicated calibre doctor on the implications of my results. It’s great to have all my data at my fingertips and someone trustworthy to connect on it.
Luis
Great team focused on offering value to their users. I'm a GP myself and quite health-conscious, and I love that Calibre offers blood tests that are not part of classic NHS panels (e.g.: ApoA & ApoB, DHEA, etc.). Learned a lot about my own health.
