EXCELLENT Based on 96 reviews Posted on Marcus HallTrustindex verifies that the original source of the review is Google. The team at youth revisited have looked after me for quite a few years now. They always go the extra mile when it comes to service. Any questions you have they are very quick to respond and super helpful. They have made getting my blood work done very easy, from finding me a phlebotomist to come to my house or a clinic near by, not to mention that the results are uploaded the very next day! Very good pricing on the tests too, I just wouldn’t go anywhere else - simply no need.Posted on Luke BrooksTrustindex verifies that the original source of the review is Google. Fantastic service. Went above and beyond to accommodate my requests some 400 miles away from their facility. Test results were ready less than 24hrs after posting my sample. Highly recommended and far superior to other well known blood testing servicesPosted on liang7079Trustindex verifies that the original source of the review is Google. Fantastic service ! Very informative tests that help athletes to stay on top of their health, and quick appointment booking for at home blood draws, and results back within 12 hrs of receiving at lab. Couldn't have asked for better. Thank you again for providing your valuable service 👍❤️🩸Posted on Anita HaylerTrustindex verifies that the original source of the review is Google. I met the family behind Youth Revisited at the Health Optimisation Summit at London Business Design Centre in Sept 2025. I was greeted warmly by the entire family when I decided to take two of the most premium tests they offered. I felt very looked after. With my international bank card I was travelling with, I was unable to pay for the tests at the Health Summit and so they allowed me to pay once home with access to online banking through an invoice. The They allowed me to still have the tests taken and on payment have my samples sent off for review. My results came back rather concerning and the entire family bent over backwards mid-weekend during a family dinner after hours to reassure me that they were beside me along the way, calling from a restaurant phone line where their mobile service was patchy, showing unwavering support by offering a retest free of charge to check the levels again, specialist referrals and a general willingness to find a solution for me with reassurance and a family like care. Thankfully I was later made aware my results weren't as alarming as first thought and from their support, they found reasonable solutions amongst a distressing journey, with genuine human connection, care and understanding. THANK YOU ALL!Posted on Adam FeatherstoneTrustindex verifies that the original source of the review is Google. Fantastic experience, really relaxing spa like atmosphere, super quick and painless - the most in depth results and explanation that you will never get from the NHS- would highly recommend so that you can begin to make adjustments to your own lifestyle
