The phlebotomist was extremely professional, and spent time going through the questions that I had for her on how to understand the results. She was punctual, concerned that I was sufficiently hydrated, and also gave me additional water.
Above all, she took time with everything.
The clinic was immaculately clean.

Good service - will use again
A very fast and efficient service in Guildford. Blood taken at 9.45 and results by 4.30pm on the same day (although was told 2-3 days). Its a really helpful service and £29 for having blood taken in the clinic is very fair. Feel more confident in the results compared to the 'at home' tests. Will use agin

Very indiscreet company
1:A constant barrage of emails advising me that my account is established, tests are being processed and now asking for a review when I still have not received the results! The endless emails are very indiscreet. Many people might glance over my shoulder - I don't want them to see I have an email from a company called One day tests! Thanks for your reply. My point which I am not suere you understood is that not everyone wants emails in their inbox from a company called one day tests. Not everybody's emails are secure/ private .

We're sorry you felt the communication was too much. We want to make sure customers know their blood samples are safe and are being processed. It helps customers with their expectations of when they will receive their results.
great professionals and fast result

Very straight forward and efficient
As there was a special offer on visiting a One Day Test centre to have my blood test taken, I went into Guildford. Very efficient and friendly nurse and so much more straightforward than doing the test at home. Results in very promptly and well presented.

Frequent Flyer here!
I have used One Day Tests for my blood tests and those for my partner for the last two years, having tests carried out every 6 months.
We both use the walk-in clinic in Guildford, and the phlebotomist there is really excellent.
The results are always delivered within the timescales promised.
I can only recommend their service without reservation and will be having tests carried out again towards the end of this year.
