PGT-A

Meaning

PGT-A stands for Preimplantation Genetic Testing for Aneuploidy, a sophisticated and widely utilized genetic screening technique performed on embryos created via In Vitro Fertilization (IVF) before their transfer to the uterus. The primary, critical objective is to accurately identify embryos that possess an abnormal number of chromosomes, a condition known as aneuploidy, which is the single most common cause of IVF failure, implantation failure, and spontaneous miscarriage. This genetic tool significantly improves the clinical probability of a successful, healthy live birth.
