Quick and easy
It's been very easy to book and I also needed to move to booking to another day without any fuss.
The blood test itself has been very quick and I had the results the day after.
The staff has been very kind.

I wouldn't recommend this place for blood tests. I paid for two tests and they were simple tests with no information. The biomarkers didn't show up and they resulted into a blank page.
You don't expect to pay over £100 for tests and come out with blank results
Waste of money!

Reply from One Day Tests - Guildford
Hi Ariana,
Thank you for taking the time to leave a review.
Apologies to hear this.
We have attempted to request further information on your order so we can look into this for you. If you would like to contact us directly on hello@onedaytests.com, we would be more than happy to assist you with this.
All of your results will be on the Health Dashboard, in the Lab File section. This is where you download and print off your results.
Next to your result, will be the reference range, so you will see where your result falls within/outside of the reference range.
We do not diagnose, as your results are in form of numbers for a GP to understand and to help towards health/medical investigations.
In the Biomarker section you will see your results in form of charts and graphs with simple generic explanations of what your results could mean. These have been put together by our GP team.
If we can be of any further assistance, please let us know.
We wish you all the best

Brilliant!!
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
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.

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.
