What DNA Testing Can — and Can't — Tell You About Your Health

Deoxyribonucleic acid (DNA) is the blueprint for every cell in your body and dictates many aspects of your health. Testing your DNA can provide valuable information about your current and long-term health so you can be proactive about your lifestyle, diet, and other factors influencing your wellness.

At RegenMed Health Centers, we specialize in DNA testing, which allows adults to learn more about how their bodies function.

Ellen Lin, MD, uses the results of your DNA testing to help you get ahead of health challenges so you can live a high-quality, balanced life. If you’re unsure that DNA testing is appropriate, read on to learn what results testing can and can’t provide.

What’s involved in DNA testing

DNA testing is a minimally invasive procedure that can enhance your health and long-term wellness.

We collect DNA from your body for testing in several ways. Dr. Lin can use a swab to collect a cell sample inside your cheek (buccal smear). She may also request saliva, blood, or hair samples to analyze your DNA.

We send the samples to a medical lab, where technicians evaluate them for specific changes in DNA, proteins, or chromosomes. The lab sends the results back to Dr. Lin, who interprets them for you and your health.

Uses of DNA testing

One of the primary reasons we offer DNA testing for our patients is to determine whether or not you have variants in the genetic code of your DNA that increase your risk for a specific disease, such as colon cancer, breast cancer, or a heart condition.

For instance, variants in certain genes can increase the likelihood of developing an inherited heart condition known as cardiomyopathy that can damage your heart muscle.  Variants in the BRCA1 and BRCA2 genes significantly increase a woman’s risk for breast cancer.

Some people may never develop a particular disease but can be a carrier for one. DNA testing can provide information about your risk for passing genetic health conditions on to your children.

You may also benefit from DNA testing as a diagnostic tool to identify underlying genetic or chromosomal irregularities that can contribute to unusual symptoms. For example, a woman under age 40 who experiences primary ovarian failure can be tested for Fragile X syndrome.

What DNA testing results can’t reveal

DNA testing can certainly provide a lot of critical information about your health, but other factors must also be considered.

During your evaluation, Dr. Lin considers your DNA test results as well as other factors that influence your health, such as your environment, diet, lifestyle choices, and social well-being, to create a personalized care plan.

Even if your DNA test doesn’t reveal any inherited risk factors for medical challenges, you still need to take steps and make healthy choices to protect your long-term wellness. Dr. Lin gives you the tools to regain control of your health and works closely with you to ensure you achieve your goals.
