Blood Tests

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 moved in January 2017 and is now located in the outpatients' department, main building, level 0. 

You can now book your appointment online and there will be some walk-in appointments available. Booking online saves time and reduces your waiting time considerably as you can book an appointment at a time of your choice and you only need turn up five minutes before to check in. Walk-in patients may have to queue for up to two hours at busy times of day. The blood test itself usually takes around five minutes.

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 operate appointment system, please see details above. The Laurels Healthy Living Centre operates an open access (walk-in) policy. For 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 staff, called phlebotomists, who are very skilled at it. 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.
