Laboratories that are allowed to work with human material are supervised by the Federal Agency for Medicines and Health Products (FAMHP).
The Leuven lab is also ISO-certified. This quality label is re-assessed every three years.
Various measures are taken in the lab to prevent sperm/eggs or embryos from becoming contaminated with bacteria or viruses. Cells are always handled in a sealed room with purified air. Couples are regularly screened for infections.
Labelling: it is extremely important that each sample is correctly labelled with the name/date of birth of the man and/or woman from whom it was taken. This is re-checked each time the sample is handled. Before each procedure, the names of the man and woman on the receptacles are checked with the couple.
