Excellent service
Excellent service. The nurse had trouble getting blood out of me (due to me being dehydrated) but she was persistent and got it done in the end.
Very happy, highly recommend the Chelmsford branch.

Brilliant service!
Would highly recommend this service! Each step was very efficient and results were received next day as informed. I visited a nurse who took my blood for this test (provided from the company for an additional cost) who was very professional but also friendly and reassuring. Couldn't fault this service at any step, will definitely be using again. A great way to find out what's going on in your body which you can't see!
