Currently, most NGS-based PGS technologies are limited in that they cannot detect all forms of triploidy, which is the presence of three, instead of two, copies of each of the 23 chromosomes in an embryo.

What does PGS not test for?

PGS Does Not Screen for Specific Diseases; PGD Does

This test is important if you or your partner have a history of a genetic disease in your family or are a carrier for a genetic disease and you want to diagnose the embryos for that condition.

What genetic disorders does PGS test for?

Preimplantation genetic diagnosis or PGD tests for single gene mutations associated with genetically inherited disease, e.g. cystic fibrosis, sickle cell anemia, muscular dystrophy, Huntington's Disease, Fragile X syndrome and many more.
