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.
