Will use Again
Pleasantly surprised at how painless and easy the blood draw was. It was expertly taken by Sophie, thank you!
The results came through really quickly and website is very good at helping interpret the results.
Will be back again for another test to see how the lifestyle and diet changes have impacted.

Brilliant service
Brilliant service. Despatched the same day I paid for it. Arrived next day. Blood taken and posted back the same day and received my results the following day. Three day turnaround.

I have been using One Day Tests in Crawley for a couple of years now and have only ever received an exceptional service. Booking online is easy, plenty of parking, friendly clean premises. I have seen Sophie the plebotomist a couple of times and she is always helpful and friendly and I don't notice the needle. A couple of times I have an appointment in the morning and I have had my results early afternoon. Great service

Ultimate Longevity test
I recently did the Ultimate Longevity Test at One Day Tests and it was incredible! The test gave me a full, detailed insight into my body and overall health – truly like a full-body MOT. The team were professional, knowledgeable, and made the whole process simple and comfortable. I loved learning about the results and how each marker relates to my longevity and performance. Highly recommend this for anyone interested in biohacking, human optimisation, or understanding their health in depth. I’ll definitely be coming back!

You can't be serious???
I posted my blood test kit to you 10 days ago and still awaiting the results? You must change your companies name to one month tests.
Another lie, why?
Nobody from your company has contacted me and I am taking legal action against you.

I have been using OneDayTests for years now. I find their service to be invaluable. They have a wide range of tests, which is great, their service is fantastic (Charlotte and her colleagues always answer my emails promptly and they are all super helpful) and Sophie, the Phlebotomist at their Crawley location which is where I always go, does a great job--I often get blood tests and can attest that not all Phlebotomists are equally by any means. Sophie makes it fast and virtually painless, very appreciated. As well, the turnaround time for their tests is very good. Thank you to all of you. I highly recommend their services.
