REQUEST AND SAMPLES TO BE SUBMITTED TO THE LABORATORY OF THE DEPARTMENT OF MEDICAL GENETICS
Use the form “Postnataal genetisch onderzoek voor constitutionele aandoeningen” if you wish to request a diagnostic or predictive test for your patient with (risk of) a congenital condition for which you suspect a genetic cause.
For the non‑invasive prenatal test (NIPT) or an invasive prenatal test, use the specific request forms (see page Forms – Request forms). Also check the acceptance criteria (general criteria below and specific criteria for prenatal tests (see the “information” tab under Genetic tests – Constitutional genetic disorders).
The form “Request cytogenomic test for patients with malignant tumour or hemato-oncologic disease” must be used to request testing for chromosomal rearrangements and changes in copy number of (parts of) chromosomes for diagnosing patients with cancer and for monitoring disease progression. Determination of donor percentage (donor chimerism) after a stem‑cell (bone marrow) transplantation must also be requested using this form.
Mandatory information on the request form:
For correct interpretation of the test result, it is important that the indication for the test is known. Examples:

General acceptance criteria for performing the genetic test: A genetic test can only be performed if it is requested by a physician. The name and first name, RIZIV number, and signature of the requester are mandatory. Testing may be refused if the sample and/or request form do not meet quality requirements. Request forms must be completed fully and unambiguously (see “mandatory information on the request form”). A description of the clinical symptoms of your patient is mandatory. The indication must be clear. You must state whether you request a test for carrier status, confirmation of a clinical diagnosis, or prediction of a condition that may manifest later in life (predictive test). The clinical information must show consistency with the symptoms of the genetic disorder for which the test is requested. Indicate whether (and which) relatives have the disease. We may contact you for additional information. Therefore, please provide your personal details clearly. The sample label and the information on the request form must clearly identify the patient—see Sample Instructions. If labeling is questionable, the sample may be rejected. It is important that the human sample is of the correct type and that it is stored and transported properly. Sample requirements are also briefly listed on the request forms. Sometimes, after consultation with the requester, a non‑standard primary sample may still be used; in that case, the result will be reported with reservations. The request will be refused if:
