Genetic Testing

2026/03/13
What is genetic testing?

Genetic testing is a type of medical test that examines your DNA (Deoxyribo-Nucleic Acid). DNA are the instructions inside your body that make you who you are. 

Sometimes, changes (called mutations) in these genes can cause health problems. These changes can be inherited, or they can occur spontaneously in an individual without a family history of the condition.

Why is it done?
This test can help doctors learn more about your health, such as whether you have or are at risk for certain inherited conditions.
Does it hurt?
Involves a blood draw for a sample of about the size of two tablespoons; minimal discomfort.
Potential risks and complications
There are no significant risks or complications associated with genetic testing. Genetic testing is voluntary and is a personal choice. It is mainly used for family screening and is typically first done on an individual who has the inherited cardiac condition.
