Very efficient and timely service
The booking and payment procedure was very straightforward.
The blood test was carried out on time very little waiting.
The results came through on the same day so extremely efficient.
There was also some follow up to ensure I was getting appropriate medical help.
I will definitely use again.

Lost blood tests and poor communication
Lost my blood tests and refused to acknowledge that for weeks, citing that they are waiting to hear from the lab on the issue

Hi Lolita,
Thank you for taking the time to share your feedback. We are sorry to hear this.
We can see that the test purchased with us does hold a slightly longer lead time, as advised during direct communication with one of our Customer Service Representatives. We are aware that all results have now been received and this matter has been resolved.
Please don't hesitate to contact our team if you have any further questions.
We wish you all the best

Best experience with blood-work…
Best experience with blood-work to date. From the moment I made the appointment, to the moment I got the results everything had been seamless. Valentina (who took my blood sample) was SO good at this, it was over before I knew it. Oh and I got all my results on the same day. I have found my go to when I want any blood test done.

Comfortable and Professional..
I'm terrified of needle but the nurse was so patient and helpful. Even had a special trick to take my blood as my very small veins love to jump around lol
Only took 2 goes which is very impressive for me.
Awesome nurse.
I visited the Branch by Liverpool station.
Website very straight forward, great time slots.
Also offer a walk in service if your push for time.

It does what it says and was efficient, easy to book and results were with me about 24 hrs later.
I wanted blood tests without having to buy the rest of the health package from a competitor and it worked well.

Cant fault this experience. Clear and comprehensive website, easy booking process, local clinics, loads of available timeslots and excellent professional friendly staff, especially the nurse who took the blood. the results werent promised the same day but they arrived via email as promised less than 5 hours after the blood was drawn. Results were clear and explained well via the portal online. Five stars easily.
