Analysis and Testing

Genetic testing is a medical process that looks into your DNA to learn more about your genes. It helps spot certain gene mutations that might link to specific health conditions.3

The test involves giving a small sample of your blood, saliva, or other tissues, which gets checked in diagnostic laboratories for genetic clues.

Genetic tests can be useful—they can tell about risks for certain diseases, help plan treatment options, and even guide decisions about having a family.

How Does Genetic Testing Work?

Genetic testing works by:

  • Collecting a sample – Usually blood, saliva, or a cheek swab. This sample holds your DNA.
  • Isolating the DNA – Your DNA sample gets checked in a lab.
  • Understanding your DNA – Experts read your DNA, examining the sequence of letters (A, T, C, and G) that make up your genetic code.
  • Looking for patterns – Experts search for specific patterns or variations in your DNA that could be associated with health conditions. These patterns might indicate potential risks.
  • Results analysis – Positive results might mean they found something worth noting, while negative results suggest clear genetic health.
  • Interpretation – The final step is understanding what it all means. A genetic counselor will look at the results in the context of your overall health, family history, and lifestyle.

After Genetic Counseling

After a genetic counseling session, the next steps involve a personalized approach to address your unique health situation.

Genetic testing may be necessary to learn more about your situation. While doing this, you can ask your counselor more questions for added clarity.

Once the genetic testing results are available, you can work together with your counselor to discuss the findings thoroughly. Whether the results are positive, negative, or uncertain, your counselor will explain the implications for your health.
