Preimplantation genetic diagnosis, also called preimplantation genetic diagnosis and screening, is a procedure applied during infertility treatment in Chennai to test embryos for genetic disorders before they are placed in the womb. PGD has nowadays been replaced by a more comprehensive category which is known as preimplantation genetic testing (PGT) which comprises methods for the genetic evaluation of embryos. The Advanced Fertility Clinic in Chennai Offers PGT, which can identify chromosomal abnormalities, single-gene disorders, and mitochondrial DNA mutations, significantly raising the chances of a successful pregnancy while minimising the risks of passing genetic diseases down to future generations.

Testing is covered under the PNDT Act.
