I went to the Guildford branch and my review is above.

I went to the Guildford branch and the lady who takes the blood samples there is the absolute best. She is organised friendly and really helpful. The service is also remarkably fast. I’ve been a few times and you could not ask for a better service. It would be perfect if they also offered a C peptide test!

We arrived early and were called before our due time. All the options were clearly explained to ensure we chose the tests best suited to obtaining the information required. We were pleased with procedure and the results were indeed sent later that evening as predicted. We would recommend if a quick determination is required.

Just excellent

Just excellent - Quick and easy to use, the dashboard has a great layout, especially when comparing data from previous periods. I have used them twice, once in 2024 and again in 2026. I will now use their service every six months to track my all my base line markers.

10/10 Experience

Easy to book online; very clear about what would be involved and the costs; great links to maps/directions; the nurse was great at her job and very personable. An altogether enjoyable experience and my results were available the very next day which was quicker than I had anticipated.

Fabulous service

Fabulous service. Easy to book, very friendly reception and phlebotomists who cater well for nervous people too. Have had several appointments at the Guildford clinic and they have been on time, helpful and friendly. The clinic is upstairs so accessibility may be an issue for some. Most results have been received same day with a few results the following day. Expensive, but you get a great service if you want comprehensive tests quickly without having to beg your GP.

I love One Day Tests

I love One Day Tests. It's a great company filling a huge gap in the market right now where getting NHS help is so limited / delayed / sadly substandard often. It is so reassuring to be able to take some positive steps in understanding your own health with One Day Tests.

The test and results were quick and easy. There was 1 bio marker where i had to pay for a separate test. This should really be included in the full comprehensive test as it is needed to calculate Fib 4 and 3 out of the 4 metrics are included. It would have been better if there was a closer location to draw blood as well.

Amazing, efficient and quick service

Had my blood taken by Magdalena she was so good, efficient and friendly. I don’t have the easiest veins and she got it first time!
Both times my HCG test was taken I got the result that night - faster and cheaper than my fertility clinic thank you!!

An excellent experience

An excellent experience. Very thorough and efficient from the start. The Guildford clinic is slightly hidden away so give yourself plenty of time to find it.
The nurse was excellent and the results were released very quickly. The private GP was great and the write up was very helpful.
