Me & My Husband came here to have our IVF screening bloods. Magdalena was brilliant, very friendly and efficient. Results only took 3-4 working days of the quoted 7 so very happy with that!!

I just wanted to say a big thank you to Magdalena at One Day Test in Guildford for making my blood test experience so great. From the moment I walked in, I felt at ease. Magdalena really knows her stuff when it comes to the services they offer and took the time to explain everything in detail. She helped me choose the best option for my needs and even suggested a few extra tests that might be useful.

She’s also super friendly and really listens, which made the whole experience feel relaxed and stress-free. Honestly, I didn’t even notice when the blood draw was done! I’ll definitely be back for my next tests – such a smooth and pleasant visit!

Used One Day Tests multiple times, results come same day they receive the samples.

Also, the Customer Service team is amazing, responding quickly to your questions. Special thanks to lovely Charlotte Heard, who is extremely helpful and kind.
