What if my child has been referred for Blood Tests by my GP?

Requests for blood tests from the GP must be made on the official blood test request forms, which your GP will provide you with.

Please note Tuesday and Thursday mornings are very busy due to specific outpatient clinics that are held on those mornings. GP referrals may therefore be waiting some time.

Does my child need to fast?

The doctor sending you for the test is the only one who can advise you if the person having the test needs to fast and for how long. (Some of the tests that the person having the test will need to fast for are: Fasting Glucose, Fasting Cholesterol/Lipids or Oral Glucose Tolerance Test)

Your doctor will advise you of anything else you might want to know.

Where do I go for Blood Tests?

The Phlebotomy (Blood Test) Department is located on the ground floor of CHI at Crumlin’s Outpatients Department (OPD). The department is signposted from the Main OPD entrance.

From Car park 1 please enter the main entrance of the OPD and turn left. At the T junction at the end of this short corridor turn right and we are straight down at the end of the corridor through the two sets of double doors. You will then see signs directing you to the Blood test area (Clinic Room 8).

What do I do when I get there?

When you arrive, please take a ticket from the machine and take a seat. A staff member will then come and take your form and this will be used to register you on the patient system. We will try to ensure that you are seen as soon as possible, but sometimes there can be a delay. When your turn comes, you will be called in to do the test.

There are certain patients that for clinical reasons must have blood tests carried out within specific time periods. These will have to be done at these times. All other patients will be called in the order that they arrived

How are blood tests taken?

The expert who takes your blood is called a Phlebotomist. The procedure is called venepuncture. The Phlebotomist will call you into the testing room. They will identify you and your child and confirm name and date of birth. The Phlebotomist will confirm the blood tests that are required based on the request on the form and will explain the procedure to you and your child.

Then he/she will draw the blood from the vein (the venepuncture). They will put pressure on the point of the vein that the needle was inserted into, to stop any bleeding, make sure your child is okay and then you are able to leave.

How do we get the results?

The results of the blood test will be sent to the doctor who ordered it. This could be your GP or a Consultant at the hospital. The staff in the Phlebotomy Department have no access to the test results and will not be able to give you any information on the test results.
