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

Ok service

The service was ok. I’d love to rave but the overall experience on the day was slightly less than I had hoped for. Unfortunately there was an accident that held up the traffic too town and that couldn’t have been foreseen, however the 8am appointment turned into 10am, and I would have been chilled about it but I got a call from customer service every 30 minutes to rearrange, again chill, except of the two people calling they kept contradicting each other. It got a bit tedious. On arrival the Chelmsford office is tucked away and it took a couple of requests to be let in. For the price I would have expected the phlebotomist to know what tests we were doing but I was asked to check what I had booked and blood was drawn against my ‘guess so’ reply, not a screen list or conformation. Overall the actual test felt rushed and chaotic. Tests came through in 48 hours, good plus, but the price of a consultation for 15 minutes was way to high especially as they didn’t say if the individual was qualified in any particular field or just a GP or pharmacist doing calls (worth clarifying) it was hard to understand some tests that were marked as not adhering to certain standards.

Easy to book online

Easy to book online. Found my nearest clinic and was able to book an appointment quickly. Day of the test was superb. Quick and easily done and test results started to come through the next day. We were able to book an appointment with an online GP to discuss the results. Absolutely perfect and will use this every year now.

Fantastic Service

The test arrived the next day. Easy to follow instructions on how to do the sample.
As I don’t like the sight of blood I was nervous, this was so easy to do that I hardly noticed the blood!
Service after the sample was received was fantastic, emails received at every step. Results clear and easy to understand too.
Will definitely use again.

A Private Blood Test

Easy to book, competitive pricing and easy to find. All instructions on the website very clear. I arrived 5 mins before allocated time, was seen straight away, completed a health check form then the blood test was done. Results received within 2 days. A great service.

Fast results can save you

They did my blood test and I had the results the next day and a warning to see my doctor urgently. I did that and ended up in hospital needing a small procedure. Without that I could have been in serious trouble.
