Non existent communication post payment.
The test results were later then the latest declared 10-working day turn around time.
Even worse after 10+ attempts on line and via email to get a status not one reply was received.
No telephone line is available. A visit to the clinic in Broadfield, Crawley, Daniel could see the sample was in the lad with no status.

Exceptional professional service
My phlebotomist was Sophie and she was absolutely lovely. Very friendly and I hardly felt a thing. There was no bruising and I received the results back within the same day. I found the service very efficient and would thoroughly recommend.

Brilliant
Brilliant! I have been 3 times now and this healthcare service is extremely efficient. It is so easy to book online. Today I was met by Sophie who always takes a thorough health questionnaire check before taking my blood. Sophie is very experienced and gentle and I always feel confident with her. She ensures my blood samples are with the laboratory, sited next door, within minutes as you are informed when they arrive there! and today my results were ready within a few hours. Thank you Sophie and all the laboratory staff

So impressed with One day tests
So impressed with One day tests. Needed a thyroid blood test urgently for an aviation medical. Booked an appointment for the next day at 1130 and I have my results that afternoon. The facility at Crawley is very modern and clean and the staff member that took my sample was so friendly and caring. Def worth the money if you need a test done quickly for any reason.
