Appointment and Registration

When you contact the secretaries to make a clinic appointment, a member of staff there will create a personal file for you. For this, you will need to provide the details below. 

If you are contacting us in relation to a possible pregnancy or pre-conception consultation, please provide this information for both partners.
  • First name and surname
  • Address (of both partners if these are different)
  • Telephone number (ditto)
  • Date of birth
  • Population register (rijksregister) number(s) (for Belgian patients)
  • If you are registered with a Belgian mutual health insurer: the name of your mutual health insurer and your membership number

Are you contacting the CMG because there is a known genetic disorder in your family? If so, please gather as much information as possible and bring it to your consultation:
  • Your family tree for at least two generations, i.e. your generation (including any brothers and sisters), and also your parents, your grandparents and any existing children already born to you,
  • The names and dates of birth of your family members,
  • Any clinical and/or genetic reports for family members who have the genetic disorder.
If you have already undergone tests in the past, please bring the results to your consultation. If you do not have these, the secretaries can request them for you.

Every time you come to the CMG, either for a consultation or for a (prenatal) test, you must first visit the Registration department so that you can register with the hospital.
Once you have done this, you should go to the outpatient department and find the Medical Genetics secretaries in the yellow zone C, level -1, route 752.

Points to remember

  • If you are contacting us in relation to a pregnancy or preconception consultation, during fertility treatment or for prenatal investigation, both prospective natural parents must register. This will allow us to request and carry out medical analyses under both names.
  • In UZ Brussel every payment must be made with a credit card. For reasons of security we do not accept cash.
  • Do not forget proof of identity (for both of you)
    • if you have the Belgian nationality, your identity card
    • if you are a foreign patient, you will need your passport for registration.
  • If you have been referred from the UZ Brussel Gynaecology department, both you and your partner must register before you report to the Medical Genetics secretaries.


Before we can start a genetic test we will need a blood sample from you and in many cases also from your partner. At PGD we also ask for samples from any family members.

  • You can go to UZ Brussel for a  blood sample collection after your consultation. We advise you to book an appointment upfront (phone number, see Contact).
    The 'outpatient blood sampling' centre is close to the 'genetics clinic', in the outpatient centre (yellow zone C, level -1, route 740).
    It is open from 7.30 am to 4.30 pm on Monday, Wednesday and Friday and from 7.30 am to 7pm on Tuesday and Thursday.
  • Alternatively you can go to your own doctor, district nurse, gynaecologist or an external laboratory.


If you cannot attend a scheduled consultation or investigation, or if you wish to cancel it, please inform the secretaries as soon as possible.
You can do this by calling us (see Contact) or by e-mail at
UZ Brussel asks you to do this at least one day beforehand. If you repeatedly fail to attend appointments or investigations, you may be asked to pay a contribution towards the cost.
