Superb, Speedy and Thorough.

Superb! A wider choice of blood tests than other companies I have used in the past (I was specifically looking for IGF-1). Thorough explanation of all the markers tested and what was covered. The process of ordering and booking was slick and effortless.
Test day, I had my blood work done in the morning and started receiving results on the same day - extremely efficient.
My health dashboard was extensive and everything was well explained.
Can't recommend them enough. Violeta at the City branch was great.

Easy to access (very close to Liverpool Street Station), well-maintained facilities. The nurse was very attentive and kind. It's a positive experience so far, and I got all the results via email the next day.

Great Experience - highly recommended

Everything went smoothly and exactly as I'd hoped. I don't like having my blood taken, but the person who did it was excellent, and I had no problems at all. The test results were quick and easy to understand on the dashboard. I've used them to refine my supplement regimen and gained confidence in my health, especially in cardio, which I couldn't get from the NHS.

Really impressive service

Really impressive service. The nurse was great (the most pain-free blood draw I've ever had!). The results came back the same day/next day and were really clear to read and understand. I was also able to send the PDF of all the results to my GP - which was really helpful. I will definitley use again.

Quick blood tests

I attended the clinic about an appointment and I was seen within two minutes. The nurse was very friendly she was able to read my blood report that I actually had the day before with the doctors next door London doctors clinic. I was advised by a friend to get an advanced thyroid check as the doctor at the clinic next door just basically said my thyroid was fine but you know yourself when there’s something wrong with your body. I got my results the same day around 9 pm in the evening I gave my sample around 1130. The turnaround was great. Communication was good. Everything was explained properly and I was able to read my results and share with my friend and I definitely recommend if you want something fast and potentially a diagnosis of where you need to improve then I definitely suggest coming here
