For blood tests and other samples.

Central Patient Lab Services (Blood tests) at Erasmus MC

How it works

Central Patient Lab Services is where you go if you are asked in an outpatient clinic to take a blood test or to provide other samples (such as urine, faeces or saliva). You don’t need to make an appointment if you’re already a patient here in the hospital.

Please make sure that you bring a valid ID document with you. You can check-in at the self-service registration kiosk opposite the reception desk. You will be issued with a day ticket and automatically added to the correct queue.

You can then take a seat in the waiting area and we will see to you as soon as it is your turn. Your number will be displayed on the information screens.

Where can you find us?

You can find us at one of the following locations:

  • Ne building, first floor
  • Ng building, first floor
  • Room SP-3480 in the Erasmus MC Sophia Children’s Hospital

Follow the signs to the correct location. You can also ask one of our hosts and hostesses in the main hall to help you if necessary.

Blood tests for children

When you arrive for a blood test, we’ll first explain to you and your child exactly what it is we are going to do. If we need to take a blood sample from a child aged less than 6 months old, we’ll do this by means of a heel prick. If the child is over 6 months old, the sample is taken by pricking their finger or arm. Which we do depends on what it is that your physician has asked for.

Sweat test

We also carry out sweat tests. A sweat test involves collecting sweat and lasts 30 minutes.
