Thanks for the review and using our service.
Lives up to its promises
I attended the Cardiff clinic on a Friday for Ultimate Longevity tests. Rebecca was friendly, efficient and explained everything well. I had notification my samples had arrived on Saturday morning and within a couple of hours the results started coming through.
There was a delay in some of them but Charlotte responded to my query in 15 minutes of my email and the remaining results arrived 2 hours later. I wish other organisations gave this level of service

Brilliant service!
Arrived 15 minutes early and went straight in for my appointment!
As someone who’s not good having bloods taken, the nurse was lovely and kept me calm! All done with no pain and was out before my actual appointment time

Sorry to hear that you feel like this way about our service. Just to clarify a couple of points. You arrived early for your appointment and our Phlebotomist actually saw you earlier than the stated appointment time that you pre-booked.
We also see from our records you received your results quicker than the stated turnaround times for the test you choose.
Great
Easy to book. The lady who took my bloods was lovely. The whole appointment took around ten minutes. Would definitely recommend and will be using in the future!

Thank you very much for the recommendation. Really pleasing to hear stories from customers like yourself that had such a positive experience using our service.
Quick, easy and helpful
Quick, easy to arrange and very efficient service. Friendly, helpful and professional phlebotomist made it easy to relax. Results came speedily to my inbox, were comprehensive and easy to understand. Follow up with their online GP was helpful and reassuring giving me oointers on what ro do next and what to ask my NHS GP.Excellent service, will use again.

A really comprehensive service
Got an appointment really quickly, blood was taken very expertly and some results were delivered by email the next day even though it was a Saturday. All results were received within the stated targets. The results were comprehensive, highlighting any that needed attention. I will certainly use them again.
