Pre-implantation Genetic Diagnosis (PGD)
What Is PGD?
Pre-implantation Genetic Diagnosis is a test performed on embryos created through IVF to check for a specific inherited condition that runs in the family. Only embryos found to be unaffected are chosen for transfer, which helps families avoid passing on serious genetic disease.
Who Is It For?
Known Gene Mutation
Couples who carry a known gene mutation, such as for thalassaemia, cystic fibrosis or sickle cell disease.
Chromosomal Rearrangement
Families with a chromosomal rearrangement.
Previous Loss
Couples who have lost a pregnancy or child to a genetic disorder.
Genetic counselling before and after testing is essential.
How It Works
After IVF
The test is performed on embryos created through IVF.
Cell Sampling
A few cells are carefully taken from the embryo at the blastocyst stage.
Genetics Laboratory
The cells are analysed in a genetics laboratory.
Embryo Choice
Results guide which embryo is transferred.
Limits and Legal Position
PGD cannot guarantee a healthy baby, and prenatal testing may still be advised. In India, selecting an embryo on the basis of sex is prohibited by law, and PGD is allowed only for medical conditions. Clinics must follow these rules.
