Find Out Why Genetic Screening and Testing May Be Right for You


Planning to start a family involves many decisions. Carrier screening and Preimplantation Genetic Testing (PGT) are tools that can provide important information and allow you to make the most informed choices.

What is carrier screening?

When you are pregnant or planning to become pregnant, you want everything to go right. While most babies are born healthy, with every pregnancy there is a small chance of having a baby with a genetic disorder. Carrier screening provides specific information about your genes, and your potential risk for passing on an inherited disorder to your child.

For people who know they are at an increased risk of passing on a specific genetic condition, PGT-M or preimplantation genetic testing for monogenic/single gene defects, can be performed prior to pregnancy to greatly reduce the risk of having an affected child. 

What is PGT-A? 

PGT-A is a way of identifying embryos with the correct amount of chromosome material to improve your chances of a successful pregnancy. When an embryo has an extra or missing chromosome or chromosome segments, that’s a condition known as aneuploidy. Most aneuploidy embryos do not result in a healthy live birth. Aneuploidy occurs across all age groups, but after the women reaches the age of 35, the proportion of aneuploidy embryos increases rapidly.
