It is important to differentiate between PGS and Preimplantation Genetic Diagnosis (PGD). While PGS screens for general chromosomal abnormalities, PGD is used to identify specific genetic disorders that one or both parents may be carriers of, such as cystic fibrosis or Tay-Sachs disease. PGD is typically recommended for couples with known genetic risks, whereas PGS is more broadly applied.
