PGT Tested Embryos

What is PGT Testing?

PGT refers to obtaining information through a biopsy about the genetic and chromosomal composition of an embryo or egg prior to the embryo transfer. The results of the PGT testing can help the IVF team to select the best embryo for the highest chance of success and to avoid transfer of embryos that will result in a miscarriage or abnormal pregnancy.

What are the goals of PGT Testing?

The goals of testing include improvement of the chances of pregnancy within an embryo transfer cycle, lowering the risk of having a miscarriage and increasing the likelihood of having a healthy baby. PGT can test for numerical chromosomal abnormalities such as Down’s syndrome, trisomies (having an extra chromosome), sex chromosomal abnormalities, monosomies (missing a chromosome) and single gene disorders such as cystic fibrosis, sickle cell disease, and many others. PGT can also identify the gender of the embryo.

What are the benefits of PGT Testing?

PGT testing for for women ages 35 and over can increase live birth rates and decrease miscarriage rates. This results in a shorter time to pregnancy. Additionally, because of the higher implantation rates of  PGT normal embryos, a single embryo transfer greatly reduces the occurrence, and related risks, of twin and triplet pregnancies.  

What are the risks of PGT Testing?

PGT does not test for all genetic disorders, syndromes, developmental problems or birth defects. It also does not guarantee the health of the embryo, implantation, clinical pregnancy or a live birth.  Additionally, testing may still be required during the pregnancy to confirm genetic factors or abnormalities.

Are there different types of PGT Testing?

There are multiple types of PGT Testing including: PGT-A, PGT-M, PGT-SR, and PGT-HLA. Ask your IVF clinic for additional information to see what is right for you.
