Blood Testing in London

Blood testing is a vital part of medical care, whether you are routinely testing to help manage diabetes and high cholesterol or need a blood test to help diagnose a medical condition. Many symptoms require a blood test, from unusual tiredness to headaches to recurring infections. We are a leading provider of private blood tests in Central London, here to support you on your healthcare journey.

Every blood test we conduct, even if you are testing for your own doctor or your own interest, is checked by one of our GPs as an additional safety measure – we are here to keep you safe and makes sure you receive the answers you need.

I've had two blood tests, both times I didn't have to wait long and the appointment was quick and I received the results same day The first time I had a critically high potassium score, but since learned that pumping my fist is a common cause of this, so I had a retest. It would have been helpful to have been told not to do this, as I did it instinctively. That said, I'll be back for my next blood test.

I've come the last few days for 3 blood tests. The team has been very professional, has not recommended or pushed for any other tests than what I want, and results have come back around 6 hours. It has been very easy to book appointments and they run on time. The office is modern and clean and I would come back for blood tests in the future if needed.

I did a silver profile blood test last Friday morning at 9 o’clock and at 1 pm I had my results by email. Very fast service and the nurse was very professional. Very happy I chose this clinic for my blood test!

I have been doing my blood tests at Harley Street Health Center for 3 years now and it’s always the best experience! They take care of hygiene so much which is the best thing you expect from a blood test center. The team is so kind, the nurse who did my blood test was so nice and friendly and absolutely pain free, I tend to have anxieties before tests but she made me feel so comfortable and calm! I have received my results same day after a couple of hours, incredible how quickly they assist you. Highly recommend!

I got a blood test done here for the first time and it was a very pleasant experience. Staff was very helpful in explaining me the types of test and what meets my requirements. I received the results much before time as was committed. Very satisfied
