can’t fault this company, it was quick and easy, and will definitely use them in the future.

Brilliant! Friendly staff, easy to book online and results arrive very quickly via email. Totally worth it for me as it was too stressful trying to get them done through the NHS and not receiving my results. This has made my life a lot easier and helped me understand what's going on with my PCOS.

Excellent service from start to finish. The booking process was stress-free, and the online chat support was extremely helpful throughout. Everything on the day was smooth, straightforward, and efficient. The staff were professional and friendly, and I received my results on the same day, which was very reassuring. I would highly recommend this service.

Test results were easy to understand and showed things that need to be fixed. These insights were well worth the money. The booking process, payment and having the blood taken for processing were efficient. Test results arrived quickly.

I recommend One Day Tests 100%. I received my blood test results within 6 hours of having my blood test. Magdalena at Guildford is so friendly and professional. I have 'difficult' veins but she always manages to take blood on the first attempt and puts me at my ease.

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 - 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.
