Genetic matching for known carriers

If you already know you are a carrier of a specific condition, our Known Carrier Match service helps you find a genetically compatible donor.

What is Known Carrier Match?

Known Carrier Match is a genetic matching service designed to reduce the risk of passing on genetic diseases to your future child. By comparing your genetic carrier report with that of your chosen donor, this service identifies potential known genetic incompatibilities. The test is carried out in collaboration with the laboratory Amplexa Genetics.

Reduce the risk of passing on known genetic disease

We compare your genetic carrier report and the one from your chosen donor to identify if he's a potential carrier of the same critical genetic conditions as you.

Free service

This service is free of charge, you only need to provide a copy of your existing genetic carrier report.

Results within 48 hours

You will get the result within 48 hours after providing your genetic carrier report.

Peace of mind

You know you are not passing on a known genetic disease.

What is a genetic carrier report?

A genetic carrier report, also known as a genetic report or carrier status report, provides a detailed overview of the mutations identified in your DNA. These mutations are described and specified using genetic terminology, highlighting the specific genes that have mutated.

Being a known carrier

You may already know that certain conditions run in your family. If you want to prevent your future child from inheriting these conditions, Known Carrier Match is the service for you.

  • You need to know your carrier status to order our genetic matching service, Known Carrier Match.
  • If you are unsure whether you already have a genetic carrier report, please contact your GP. 

What is a match?

A match means that your chosen donor is not a carrier of the diseases included in your genetic carrier report.

Although Known Carrier Match is a highly reliable technique, no test is 100% accurate, and there is always a small residual risk. In addition, the test cannot detect spontaneous mutations that may occur in the egg, sperm, or foetus. 

The process is simple

Follow these four steps to order a Known Carrier Match:

    1. Please create an account or .
    2. Go to our donor search and select a donor.
    3. When adding the donor to the cart, you can add our Known Carrier Match at no extra cost. You'll have to purchase at least one straw.
    4. After placing the order, you will receive an email with a link to upload information about your carrier status.
    5. If the donor is a match, we will ship the straws to your clinic or storage, according to your request.

Results and matching

  • The test is carried out in 48 hours on weekdays, except for Danish public holidays*.
  • You will be notified by email as soon as we have completed the tests. This way, you can quickly find out if the donor you have chosen is a match for you.
  • If the donor is not a match, the test will be repeated with a new donor of your choice.

    *You will be informed if the results take longer due to special testing requirements.

Known Carrier Match is a highly reliable method of finding a compatible donor. No test or matching method can detect 100% of mutations. Also, Known Carrier Match cannot account for spontaneous mutations that may arise in the egg, the sperm cell or the foetus. However, this remaining risk is very small.

You can only use the Known Carrier Match service if you already know your carrier status and have a genetic carrier report. If you don’t have a genetic carrier report and wish to have one, we recommend you contact your GP.

Known Carrier Match can only be performed before we ship the straws to your clinic.
