What is genetic testing?
Genetic testing is a medical test that can find changes in your DNA. The results of a genetic test can help determine the cause of a heart condition. It can also help determine your risk of developing or passing on a heart condition. Since genetic testing is complicated, our patients meet with a physician who is also a genetic counselor to better understand the benefits and limitations of genetic testing.

How is genetic testing done?
Genetic testing involves having a small amount of your blood drawn. Once your blood is drawn, the blood will be sent to a genetic testing laboratory where it will be analyzed. You do not need to fast before having blood drawn for genetic testing.
How long does it take to receive genetic testing results?
Typically genetic testing takes four to six weeks from the date of your blood draw. This time may vary depending on other factors such as processing the sample in the laboratory.
