I had a great experience with MSI Clinics. Very professional, fast and great customer service from Lindsay.
Stephen Taylor
Brilliant PCR test £249 might seem steep for a PCR test but I had my results within 2hrs - and that's on a Sunday. Cannot fault the professionalism and service on offer. I'd use again, no doubt.

Loz Howard
Absolutely fantastic service. Exactly as advertised, the results were back within the 3 hours. Staff were very friendly and accommodating and the whole process took less than ten minutes. Would recommend to all.
Edward Jessel
Excellent service! My wife and I used MSI clinics and I can’t praise them enough. Process was really simple, all of the tests (6 in total) all came back within the timeframe and their customer service was brilliant.

Jan Johnson
Excellent service, I cannot rate it high enough. I had a test with another clinic and they didn't give me the test I needed (PCR) to fly with Singapore Airlines so I had to quickly get another today (the day I am flying}. Every aspect of the process with MSI was easy and they met the three hour turnaround for the test. The lady I spoke to on the phone and the lady who carried out the test were both so friendly and helpful and no question was too hard or too much bother to answer. Thank you MSI you have put a big smile on my face after an awful day and night when I realised I didn't have the correct PCR test to fly with Singapore……. Later the same day I am now successfully through check in and if I hadn’t got the PCR test they would have turned me away - so if you are flying to Singapore only get PCR!
Good service Nice people, efficient service. Always got my results back on time
