When should a couple consider genetic testing?
Genetic testing in an IVF cycle can help to ensure a genetically normal and healthy child, especially if one or both partners are carriers of genetic disease or are at high risk for passing the disease to their baby.
Other cases where genetic testing can help –
- female partner is older or has poor egg quality
- couple has experienced failed IVF cycles
- history of recurrent miscarriages
- unexplained infertility
What is Preimplantation genetic diagnosis?
Preimplantation Genetic Diagnosis or PGD involves screening of IVF embryos for a specific genetic condition before the embryo is transferred to the mother’s uterus. The procedure screens for numerous genetic diseases that involve chromosome number abnormalities. The goal is to select the healthiest embryos for transfer, improving the chances of conception and a healthy birth. PGD test results become available within 7-10 days.
What test do I take to see if I am a carrier for genetic disease?
You can undergo carrier screening to test whether you are dominant or recessive carriers of a specific genetic disease.
Who is an ideal candidate for genetic testing?
For couples who are known carriers of a genetic disease, genetic testing should be done using PGD. The following women are recommended to go for PGD –
- women aged 40 or older, who may be at an increased risk of Down Syndrome
- women with poor quality eggs
- women with a history of recurrent pregnancy loss
- women who have experienced multiple unsuccessful rounds of IVF
- women who have had an abnormal fetus or child
- couples who want to decide the gender of the child for family balancing purposes
