The Genetic Compatibility Test (GCT) is a test to identify altered genes. It is developed from a DNA analysis of blood or saliva, matching the sample of the father or sperm donor with that of the mother or egg donor. This test minimizes the transmission of genetic diseases to the children. Specifically, a GCT can prevent the transmission of around 400 genetic diseases.

This test can be carried out both in couples who seek pregnancy naturally and on those who use any assisted reproduction technique.
