From the introduction of preimplantation genetic testing (PGT), science has been trying to find ways to examined the genetic composition of embryos without performing a biopsy of their cells. In the last years, research into this field has intensified and several genetics labs abroad have developed platforms for analyzing chromosomal anomalies (PGΤ-A) in blastocysts from alternative DNA sources of their cells. This is a genetic analysis of the cell-free DNA in the culture media where the embryos develop during IVF.

This procedure is known as non-invasive PGT (niPGT) and will soon become a reality. This amazing prospect will eliminate the need for an embryo biopsy and facilitate access to embryos for chromosomal anomaly testing throughout all the IVF cycles. In this case, niPGT will be non-invasive, accurate and affordable.
