Absolutely fantastic experience - Seamlessly managed and was seen straight away (despite being early) and had received all the results by the evening. Would not hesitate to anyone needing private bloods and quick results.

Very efficient and friendly service
Very efficient and friendly service. The results started to be emailed to me that evening.
I would recommend this service if you have any worries about your own health concerns
. It circurcumvented the tedious long waits initiated by your first appointment to your gp, with no wait for the tests and almost instant results.

Awful Communication and No Medication
Had all the tests, very quick results, had my GP consultation and paid for TRT treatment, one week later no medication, no communication, no replies to emails and impossible to get through on the phone. Not impressed at all

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.

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.
