What is the genetic compatibility test?

This state-of-the-art technique, also known as genetic matching or carrier study, compares the genetic analysis of both partners to ensure that they do not carry the same recessive mutation and to reduce the risk of the embryos suffering from a relevant genetic disorder.

Almost all of us carry genetic alterations that usually do not involve any disease. But if you and your partner share the same recessive mutation, there is a risk that the baby will have a significant genetic alteration.

When is it used?


Included in all treatments

We include this test in all our embryo culture treatments at no extra cost. We can detect up to 16,595 different mutations.

Before the start of treatment

When you are about to start an assisted reproduction treatment or the search for pregnancy by natural means.

Family history

When there are cases of inherited genetic diseases in the family of one or both partners.

In case of consanguinity

When the couple are related to some degree.

Benefits of the genetic compatibility test

It prevents hereditary diseases, enabling conscious decisions about reproductive desire.

It offers security and peace of mind by knowing about the genetics of both partners.

It reduces the risk of complications during pregnancy and in the newborn.

How is it done?

It is a simple technique that involves drawing blood from both partners to obtain DNA samples and sending them to a specialised laboratory where possible genetic mutations are identified. The genetic profiles are compared to detect matches for recessive and X-linked mutations and a detailed report is produced explaining the findings, including any identified risk of genetic diseases and recommendations for the couple.

The time to obtain these results is about 4 to 5 weeks, so we usually do it some time before the start of the treatment.

What happens if the result is positive?

In rare cases both parents carry the same genetic condition. When this happens, there are different reproductive solutions.

• Opt for reproductive treatment with Preimplantation Genetic Diagnosis (PGD).

• Gamete donation: eggs or sperm.

FAQs about the genetic compatibility test


What is a genetic compatibility study?
It is a test that analyses the couple’s DNA to detect recessively inherited, X-linked genetic mutations that could be passed on to their children.
Who should have it done?
It is recommended to any woman or couple who are going to start treatment with their own gametes. But especially couples with a family history of genetic diseases and consanguineous couples (with some kind of kinship).
How much does the genetic compatibility test cost?
At IGIN the genetic compatibility study is included in the price of all treatments that require it: IVF-ICSI, Preimplantation Genetic Diagnosis, Egg Donation, Double donation or ROPA method.
How is it done?
DNA samples are taken from both partners, analysed in the laboratory and compared to identify possible genetic mutations.
Which genetic diseases does this test detect?
It detects up to 16,595 different mutations that can lead to more than 300 hereditary diseases, including cystic fibrosis, fragile X syndrome, sickle cell disease, spinal muscular atrophy, Tay-Sachs, thalassaemia, Canavan disease, Bloom syndrome, Wilson’s disease and others.
What are the benefits?
It can prevent hereditary diseases, enable informed planning, and increase success rates in fertility treatment.
How long does it take to get the result?
Results are usually available in 4 to 5 weeks. This is why this test is performed before starting treatment.
