PGS is a precautionary measure used to detect embryonic chromosomal abnormalities, even if neither parent has any known evidence of a genetic abnormality. This procedure checks for chromosomal abnormalities such as Down’s syndrome (trisomy 21) and changes in chromosomal position (translocation).
PGD is a genetic test of an embryo for a particular genetic mutation when one or both biological parents already know that a genetic abnormality is present.
Is Preimplantation Genetic Diagnosis (PGD) right for me?
PGD is recommended for couples who have a genetic predisposition and / or are likely to pass through known genetic abnormalities. Couples with an aneuploid (abnormal number of chromosomes) family history leading to miscarriage, birth defects, or Down’s syndrome can be evaluated. In addition, families with single defects such as cystic fibrosis, sickle cell anemia, and muscular dystrophy may consider PGD testing. Through this procedure, highly trained laboratory personnel at the Vardhan Fertility will determine which embryos are unaffected and therefore most suitable for uterine transplantation.
