We provide blood test services for adults and children in separate clinics in the hospital:
Blood tests for people aged 16 and over
The GP blood tests unit is located in the outpatients' department, main building, level 0.
Mondays and Fridays are the busiest days of the week for the blood test department. If you are able to be flexible, please attend on Tuesday, Wednesday or Thursday.
A limited number of walk-in appointments are available each morning, but these will be closed as soon as the clinic reaches capacity. Wait times for walk-in patients can be more than two hours at our busiest times.

Frequently asked questions:
Why do I need a blood test?
Blood tests are often needed for your doctor to work out what is causing your symptoms. They may also be needed to check that treatment you are on is being effective. There are a very large number of things that can be tested from a blood sample and the ones your doctor is testing for will be written on the form you were given. If you want to know more about the tests, you can visit Lab Tests Online at www.labtestsonline.org.uk where you will find a wide range of information.
Do I need an appointment for my blood test?
At North Middlesex University Hospital we now have an appointment system for adult blood tests (people who are aged 16 or over) . Please see the details above.
The Laurels Healthy Living Centre operates an open access (walk-in) policy. For adult patients who are not fasting, the afternoon or early evening is the best time to come as it is usually least busy then and you may be seen in as little as 10 minutes. Monday mornings are usually the busiest times, so please avoid these if possible.
What happens during a blood test?
At the North Middlesex University Hospital and the Laurels Healthy Living Centre your blood will be taken by a group of skilled staff, called phlebotomists. It is normally a quick and almost painless procedure.
The phlebotomist will take the blood from the crease of the elbow of the arm you use least. This normally has a vein that can be accessed easily (you can normally see this vein as a blue line if you look at your arm). A strap is placed above the elbow and tightened slightly to increase the size of the vein. A needle is placed in the vein and blood is sucked into an attached tube. After taking the blood the phlebotomist will use a cotton wool pad and tape to cover the spot the needle entered to prevent any bleeding. In children, the phlebotomist may use an anaesthetic spray before taking their blood to make it even easier.
Some people are more difficult to take blood from, and a small minority of people can bruise easily. This can often look alarming but will normally fade within a day or two.
When will the tests be ready? Who will give me my results?
We begin testing your blood on the day it is taken. Most results are ready on the same day but some can take several days to be completed. All the results are sent to the person who wrote your request form, usually your GP.
Glucose tolerance tests
If you are having a glucose tolerance test please, please book it online on the link above.
