Known Carrier Match helps determine whether your selected donor carries the same genetic condition as you. By comparing your genetic carrier report with the donor’s genetic profile, we can help reduce the risk of passing on certain inherited conditions to your future child.

Known Carrier Match is a genetic matching service for people using donor eggs for fertility treatment. It compares your genetic carrier report with the genetic information for your selected egg donor.
The purpose is to help reduce the risk of passing on a known inherited condition to your future child by checking whether you and the donor carry the same relevant genetic variants.
We offer Known Carrier Match in collaboration with Igenomix, a laboratory specialised in genetic matching.
We compare your carrier report with the donor's to identify whether you share carrier status for the same condition.
Results are ready within 48 hours after you submit your genetic carrier report.
Genetic matching gives you clear information, so you can make a more informed donor choice.
Known Carrier Match is relevant if you:
If your chosen donor is not a suitable genetic match, you can select another donor and repeat the matching process.

A match means that your chosen egg donor is not identified as a carrier of the same genetic condition listed in your report.
Genetic matching is highly accurate, but no test can remove all risk. A small residual risk will always remain, as some rare or spontaneous genetic changes cannot be detected.
If the results show that your donor is not a suitable match, you will need to choose a different donor. We will perform a new Known Carrier Match with that donor at no additional cost.
You need to have a genetic carrier report confirming your carrier status to use Known Carrier Match. If you have not yet been tested, we recommend speaking with your doctor.
You can submit any genetic carrier report that confirms you are a carrier of a recessive genetic condition. We accept reports in all languages.
Egg donors from European Egg Bank are thoroughly screened before they start donating eggs. Learn more about our rigorous and comprehensive screening process.
