Preimplantation genetic diagnosis (PGD)
Preimplantation genetic diagnosis is performed on fresh embryos before their vitrification in order to identify genetic abnormalities and prevent passing them to their future child. We offer the NGS method (Next Generation Sequencing) of PGD which gives the high accuracy of detecting chromosomal pathologies before the implantation. It allows to receive the result which screen 24 chromosomes and will be 99,9% precise.
PGD by NGS method is done on 5-day embryos obtained as a result of IVF. A trophectoderm biopsy for each embryo will take place for the further evaluation. While the material is being tested, embryos are frozen and stored. In ordinary IVF cycle, embryologists select embryos to transfer based on their morphology which doesn’t exclude genetic abnormalities. If you decide to use preimplantation genetic diagnosis, it will be possible to detect the presence of the problematic gene and choose embryos of the best quality to transfer.
You should keep in mind the duration of PGD, as it takes up to 21 working days to receive the result. We offer testing of all embryos received from the fresh cycle.
PGD test is also available for family balancing aiming at sex selection.
