Absolutely amazing service

Went to the Chelmsford clinic for a full blood count which was done by Kerrie. She was such a smiley caring person and put me at ease ... a credit to the company.
I received my results the following day and quite easy to understand on the dashboard. A couple of markers were high so arranged the doctor video appointment... so pleased I done this for the £65 charge. Dr Adedeji was great and fully explained the blood tests in full and how to correct the high readings.
This service was amazing and so pleased I chose this company. Will use again in 6 months to monitor any progress.

I am very satisfied with the services of this center. I was greeted kindly, and the nurse who performed the collection showed a lot of patience and precision (a big plus for those who are afraid of needles!). Everything is well organized, although the reception was a little crowded, the flow of patients was managed efficiently. A 10-star medical center!"

Excellent service from Chelmsford office. Kerri was friendly, welcoming and able to explain the procedure in a really straightforward and helpful way.

The turnaround time on the results was super fast, which meant that I was able to get my prescription quickly.

Very good service would recommend

Very good service get a few try’s to repeat test if doing at home if not going to the clinic for a blood draw is very quick and simple for a small charge. You get the results next day by email then it’s up to you what you do with the information. They will flag up things on test that need investigation. I would use again and recommend to anyone who wants answers quickly

Non UKAS accredited tests

The service itself was good - the ease of booking/rearranging an appointment and the professionalism of the nurse. Unfortunately, although they are a “UKAS accredited” lab, a lot of their tests are not. They also use methods which are positive bias. They should CLEARLY include in their advertisement if a test is UKAS accredited or not (not via a tiny tab at the very end of the page that you would not know exists unless explicitly directed to). In my case, it is for IVF purposes. The fertility clinic will not accept it. The result isn’t worth the paper it is on.

Dear Michelle, Thank you for sharing your feedback. Firstly, we are pleased to hear you feedback on our service, specifically the ease of booking and our Phlebotomist who took your blood sample.

In reference to your other points raised, the AMH biomarker is not currently UKAS accredited, however we do follow UKAS ISO 15189:2022 guidelines for this biomarker. We run a wide range of quality assurance criteria and audits to ensure the accuracy of results. This includes our reference ranges reviewed and signed off by our Biochemistry Clinical Consultant.

We have highlighted a bias for the assay so that if on-going monitoring is required then our customers are made aware. Each analyser and AMH method will provide a slightly differing result, and therefore it is important that the AMH used for monitoring is always analysed at the same laboratory to allow for analytical and biological variation.

We also appreciate your feedback about how we reference on the website the small volume of tests that are not currently UKAS accredited. We will review and see how we can make this clearer.

So glad we found one day tests

So glad we found one day tests. My husband had various tests from GP over 2 years & nothing was picked up. He was extremely unwell.
We had the full ULTIMATE LONGEVITY test. It picked up straightaway the problem. We were then able to give the GP the results and be treated for a condition that they would never have found. Well worth having and would recommend. The service was great, the clinic staff were super friendly and made my husband feel at ease. Thankyou
