Pregnant patients are offered blood tests to identify the chance of certain genetic conditions, such as Down syndrome, and the predicted sex of the pregnancy, if desired. These blood tests are considered screens. The purpose of a screen is to identify pregnancies that are more likely to have a genetic condition and then offer more robust diagnostic testing either while the person is still pregnant or after birth.

We are all linked to our relatives through our genes. Our parents pass down genetic information that influences traits like hair texture, eye color, height, and even the likelihood of developing conditions like diabetes.

Environmental factors also play a significant role. For example, while someone's genes may predispose them to be tall, if they do not have enough nutrition growing up, they may be shorter than their genes would suggest.

Genetic information can offer valuable insights into our health and that of our children. A genetic counselor can assist in reviewing your family history to identify potential inherited conditions.
