What is done in a PGD?

The steps to be able to carry out a preimplantation genetic diagnosis (PGD) in the embryos after in vitro fertilization (IVF) are the following:

Embryo biopsy
one or more cells are extracted from the embryo depending on whether it is on day 3 or in the blastocyst stage.
Tubing
The extracted cell or cells are placed inside a tube with great care so as not to be damaged or lost.
Genetic analysis
DNA from cells is extracted and analyzed with different genetic techniques, such as array CGH or PCR, among others.
Assessment of results
once the results are obtained, it is assessed which embryos are healthy and which are carriers of mutations or aneuploidies.
