Amazing experience far better than… Amazing experience far better than other providers what sets them apart is their customer service and turnaround time such good service from the outset right through to dealing with any questions with the forms and results.

Brilliant staff and always reliable After using MSI clinics countless of times for our international clients (Fit to Fly tests) we recently used them to do urgent 3hr PCR tests for almost 60 of our employees. Emily at MSI was so helpful and I was hugely impressed with their flexibility and ability to get all of our team tested and results sent within the time quoted. I've used countless PCR clinics in London and MSI are by far the most reliable and best people to work with.
