PGT-A, or Preimplatation Genetic Testing for Aneuploidies, is a genetic test performed during your IVF cycle with the goal of improving your chance of getting pregnant and having a healthy baby.
PGT-A works by looking at the amount of genetic material within IVF embryos. This genetic material is housed within structures called chromosomes. Chromosomes are very important for healthy growth and development.
Embryos with the incorrect number of chromosomes typically do not result in a successful pregnancy or may lead to the birth of a child with a genetic condition.
Embryos with the correct number of chromosomes have a better chance of leading to a successful pregnancy.
PGT-A identifies embryos with the correct number of chromosomes, so we can select the embryo with the best chance of leading to IVF success.
PGT-A can sometimes be referred to as PGS, or preimplantation genetic screening.
