1 in every 100 babies born presents some kind of genetic disease. With the CGT 547 we can detect up to 600 diseases.
Genetic diseases cannot be cured, but they can be prevented with the CGT 547.

When is it recommended?

We all have alterations in our genes, and with the CGT 547 we can find out if these alterations could lead to our children having a genetic disease. The test is recommended in the following cases.

  • Prior to an assisted reproduction treatment: it is advised in order to know the risk of transmission so that the best type of treatment can be decided on in each case.
  • Prior to a treatment using donor eggs or semen: in order to be able to select a donor who is not a carrier of the same mutation as the member of the couple who is providing the gametes (ova or spermatozoa) we carry out the test on our donors.
  • Before trying to become pregnant naturally:for any woman who wants to become pregnant, so that she knows the risk of passing on possible diseases to her child.


90% of patients who undergo an assisted reproduction treatment at IVI become pregnant.


IVI is a pioneer in the latest assisted reproduction technology in order to present the best results.


97% of our patients recommend IVI.
IVI provides personalised care and support during all stages of treatment.


We are not the most expensive choice. We offer the most treatment options in order to achieve the best results.

What is the CGT 547?

The Compatibility Genetic Test is a test that allows us to identify the presence in future parents of genes that cause diseases which they risk passing on to their children. Carriers are usually healthy, but when both parents are carriers of a mutation of the same gene it is possible for them to have a child affected by a particular disease. With this test we can detect up to 600 diseases.

How is it done?

The test is carried out on DNA obtained from blood samples from the father and the mother. The results come through in a month, and we can then find out the probability of your child suffering from a genetic disease.

CGT 549

Why take the test?

Because it reduces the theoretical risk of having children who are affected by any of these genetic diseases from 1 in 100 to approximately 1 in 30,000. Genetic diseases cannot be cured, but they can be prevented with the CGT 547. Every year, many parents are surprised when their baby is born with some sort of genetic disease. This happens because in order for the disease to manifest, the child has to inherit an affected copy of a gene from both its father and its mother. When both parents have only 1 copy of the mutation, they are carriers of the disease but are themselves healthy.
Our main objective at IVI is for our patients to have healthy children.


What happens when a mutation is detected?

When a mutation is detected in one member of a couple, nothing is done unless the other member of the couple has a mutation in the same gene. This would result in there being a high risk of having children who suffer from the genetic disease.

In that case, the options for conceiving a child who is not affected by the disease are:

  • Treatment with in vitro fertilisation and Pre-implantation Genetic Diagnosis: for the majority of these diseases, we can use this technique to determine which embryos are affected and implant in the mother only those that are free of the disease.
  • Gamete donation: we can opt for an assisted reproduction treatment using sperm or eggs from a donor who is not a carrier of the disease.
