One Day Tests - Crawley Reviews 

It was so satisfactory driving there 20 minutes for 10 am, 5 minutes, done, results at 3 pm!!!

After having my blood tests back from the doctor I had high LDL yet low triglycerides and good HDL. I also scored well on HbA1c and had normal blood pressure. The LDL worried me so I paid for an ApoB test with One Day Tests. The test kit arrived quickly - it was easy to do and well explained and easy to post back. My results came through very quickly. All in all a great service where you don’t feel you can easily get these tests from the doctor.

Afternoon Charlotte and the team

Brilliant service, this is the first time I've used you, and I must say I'm impressed, I took my blood test early in the morning, went to the post office that morning, and within 48 hours the results were in my emails, which I have now acted upon, and I feel much better, thank you so much for your support

Bought a testosterone test at a discounted price. Received everything needed for the home testing quickly and with clear instructions. Lots of step-by-step email communications during the process. Received my results via email very quickly.

Great service. Good advice on getting the sample across in the shortest possible time. Prompt test results.

An extremely good experience. Booked the day before for extended blood test. Sophie in Crawley had no problems finding my deep vein and I was in and out in under 10 minutes. I would definitely use this company again no problem.

I was so impressed with One Day Tests and from the advice and understanding I was given at the Crawley clinic. The booking system was easy to navigate and I could get an appointment for the following day. I was anxious but Martine was amazing and kept me calm and reassured whilst I had the blood tests. I also had a zoom call with one of the Doctors the following day and I now have a plan in place. Thank you again to One Day Tests.

Very good and quick service

Very easy to get a booking. Everythingvran to time. The clinician was excellent. Results came within SLA. Great service.

I recently used One Day Tests for a Longevity blood test and a GP consultation. I had my blood taken at the Crawley site, which was easy to find and had plenty of free parking. My blood was taken from Sophie, who is lovely. It was quick and painless and Sophie made me feel very relaxed. The results all came through within about 16 hours and I then booked a GP appointment to go through the results. The GP was called Rhos and he was highly knowledgeable and explained everything to me clearly. My consultation results were then sent to my GP practice, which I gave permission for. The service from One Day tests was amazing from start to finish. Highly recommend and would happily use again in the future.

The service was great! The arrival of the test, the filling the test and the speed of the results were top drawer!

Great service and quick reliable results

Friendly lady and great service did what they need.

Always happy with One Day Tests.
They’ve always used the butterfly needle on me and they’re so gentle I’ve never had any pain or bruising.
100% recommend

This service was quick and easy to book, hood location, parking and friendly staff. The results were delivered timely and with explanation.
Would recommend.

Everything was handled very promptly. The instructions were very clear, as were the results that came very quickly. I was very happy with the whole experience.

Very disappointing experience with One Day Test during an already stressful IVF process.

Before purchasing their IVF Viral Screen, I specifically contacted customer services to confirm the testing was UKAS accredited because this was a requirement for our IVF clinic. Based on the assurances given, we went ahead and paid for the testing.

The service is advertised as containing the IVF virology blood tests “usually requested by the clinics”, so we reasonably believed the results would be suitable for IVF treatment requirements.

However, our IVF clinic later rejected the results because the virology testing did not meet the required UKAS accreditation standards. We were then forced to urgently repeat the blood tests elsewhere at an additional cost of £552 to avoid delays to our IVF treatment, on top of the £347 already paid to One Day Test.

What was particularly frustrating was the lack of transparency throughout the process. The reports were branded with One Day Test and Sussex Pathology, with no clear indication that the virology testing had actually been outsourced to another laboratory. It took weeks of emails and a formal complaint before this was finally clarified.

Despite the financial loss and stress this caused, One Day Test refused to provide a refund or acknowledge that the tests were not suitable for our clinic’s requirements, even though we had specifically checked the accreditation position with them before purchasing.

IVF treatment is stressful enough without additional confusion, delays, and unexpected costs. I strongly feel clearer information should be provided to patients regarding outsourced testing and accreditation scope before purchase.

Update following the company’s response dated 13/05/26:

My concern was never whether a UKAS-accredited laboratory existed somewhere within the testing pathway. My concern was that, despite specifically checking accreditation with your customer service team before purchase, it was not made clear that the virology testing was outsourced, nor that Sussex Pathology’s UKAS accreditation did not cover virology testing.

The test reports themselves were branded with One Day Test and Sussex Pathology, and our IVF clinic subsequently rejected the results because the virology testing did not meet their required UKAS accreditation standards for IVF treatment.

As a result, we had to urgently repeat the tests elsewhere at an additional cost of £552 to avoid delays to our IVF treatment.

It also took several weeks and a formal complaint before the outsourced testing arrangement was clearly explained to us. Unfortunately, despite the financial loss and stress caused, no refund or resolution was offered.

Good and reliable service

The whole thing was easy and straightforward. I attended the clinic for the blood test and parked with ease. The offices were smart and the phlebotomist I saw was efficient and polite. I received the results within three hours. Great!!
