A genetic test might be able to tell you for certain about you or your child’s genetic makeup. For some people this relief from uncertainty is very important, even if the news is bad. If the news is good, such as a mild prognosis, it can mean a tremendous sense of relief. A genetic test can help diagnose a genetic condition. When someone has an accurate diagnosis, the appropriate treatment can be given. If a genetic test tells you that you have an increased risk of developing a condition later in life (such as breast cancer) you might be able to go for more regular check-ups, or take other measures to keep the risk to a minimum.
