When Hospitals Use Genetic Testing

We use genetic testing on tumor tissue to find specific mutations that drive cancer growth. These results show us if your cancer will respond to targeted therapies that attack those specific changes. By focusing on your unique biology, we avoid treatments that are unlikely to work. This helps us choose the most effective drugs for your specific diagnosis.

Doctors use pharmacogenomics to understand how your body processes different drugs. Your DNA can influence whether a medication is broken down too quickly or too slowly, which affects your safety and comfort. This testing prevents severe side effects and ensures you receive the correct dose on your first try. It is especially common when prescribing blood thinners or certain antidepressants.

If you have a strong family history of certain illnesses, we perform germline testing using a blood or saliva sample. This checks for inherited genetic changes that increase your lifetime risk for conditions like breast or colon cancer. Knowing these results allows us to create a personalized screening schedule to catch potential issues early. We often involve a genetic counselor to explain what these findings mean for you and your family.

For infants or children with unexplained symptoms, we often use whole exome sequencing. This process examines the protein-coding parts of your child's genes to identify rare disorders. It often ends a long diagnostic journey by identifying a clear cause for developmental delays or physical challenges. Having an accurate name for a condition allows us to focus care rather than guessing at treatments.

Genetic testing can be expensive, and insurance coverage varies significantly depending on the specific test. We will always seek prior authorization from your insurance company to ensure the test is medically necessary. Your genetic data is protected by strict privacy laws, but we always discuss who will have access to these reports. You have the right to decline any test if you have concerns about the process.
