Preimplantation Genetic Testing for Chromosomal Structural Rearrangements

What Is Fetal

Preimplantation Genetic Testing for Chromosomal Structural Rearrangements?

Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) is a genetic test designed to ensure a pregnancy that is not impacted by any changes in the size, position, or structure of chromosomes (known as chromosomal structural rearrangements) in a couple with a chromosomal rearrangement.

Chromosomes are tightly coiled structures that enclose genetic material. Any chromosomal rearrangement can mean that the embryos do not have the correct genetic information that is required to lead to a successful pregnancy.

PGT-SR was formerly known as preimplantation genetic testing (PGT).
