Prenatal Genetics and Counselling
What is Prenatal Genetic Counseling?
Prenatal genetic counselors work with individuals, couples, or families who have an increased chance of having a child with a birth defect or genetic condition.
Those who are already pregnant or are considering having a child in the future can meet with a prenatal genetic counselor to learn more about the condition in question, understand their risks more clearly, and discuss options for prenatal screening, testing, and/or assisted reproduction techniques such as sperm and egg donation.
During pregnancy, if a baby is found to have a birth defect or genetic condition you may be referred to a prenatal genetic counselor. The counselor will help the expecting parent(s) understand the medical information, what to expect, how to prepare, and options.
Prenatal counselors also help many families who do not have an increased chance of having a child with a birth defect or genetic condition to understand prenatal screening and testing options. Procedures such as blood tests and ultrasounds may be able to give a better idea if a developing baby has a chance of having birth defects or a genetic condition.
