The non-invasive embryonic or preimplantation genetic test, also known as niPGT-A, allows the chromosomal composition of the embryo to be determined without the need for an embryo biopsy. Therefore, it does not require embryo manipulation and the embryo is not damaged.
The process for non-invasive preimplantation diagnosis begins with in vitro fertilization to obtain embryos. These embryos are kept in culture until day 5 of development and transferred to another plate. It is then possible to take the drop of culture medium that will be sent for analysis.
Once the results are obtained, priority will be given to the embryos with the highest score to be transferred since they will be the healthiest.
