Get to know your baby beforehand. A genetic test detects and prevents the spread of diseases due to the genetic and chromosomal conditions of the embryos.
A Preimplantation Genetic Test (better known as PGT) detects genetic and chromosomal alterations in the embryo before it is transferred to the uterus. There are different types of PGT exams according to the conditions of the patient.
PGT-A: Detects numerical abnormalities in the chromosomes. The genetic load of the embryo is analyzed to count if there are more or less chromosomes; it also traces the existence of the X or Y chromosome to know the sex of the embryo.
PGT-M: Detects monogenic diseases, which are those caused by an alteration or mutation in the genes, hence analyzing the presence of different hereditary diseases.
PGT-SR: Detects structural alterations. This test is done when someone in the couple is a carrier of a chromosomal alteration such as breaks, misunions, translocations, duplications or other structural rearrangements that can affect the embryo.
