Genetic Testing Basics

Genetic testing can empower people with information they can act on. But what exactly is genetic testing? And is it right for you and your loved ones?

What is Genetic Testing?

Think of your body as having a unique instruction book: your genes. Genetic testing is like a spell-check for those instructions, looking for any changes or “variants” that might be misspelled or missing. These variants can sometimes explain the underlying cause behind unexplained symptoms, developmental delays, or health challenges that have gone unanswered for years.

Sometimes, these variants are passed down from parents or grandparents. But many times they are happening for the very first time in a child – with no family history at all.

Genetic testing may help find these changes in you or your loved one’s genes. And it’s actually quite simpler than most people expect. A genetic test uses a sample of blood or saliva sent to a specialized lab where scientists analyze the DNA and send a detailed report to your doctor.

Why It Matters

For many families, a genetic diagnosis connects them with answers they’ve spent years searching for. A genetic diagnosis can connect families with three things at once:

• Answers: Families finally have a name for what they’ve experienced — often shortening years of the diagnostic odyssey.

• Community: Connection to other families, experts, and organizations who understand exactly what they’re going through.

• Pathways to Care: Expanded care, more targeted treatments, and opportunities to participate in life-changing research.

Genetic testing doesn’t just provide answers — it opens doors.

And yet, too many families don’t know that it’s an option. Geographic barriers, limited awareness, lack of access to specialists, and insurance challenges can create major hurdles for families who need answers the most. That’s why raising awareness about genetic testing matters. Because every person has access to the answers they deserve.

Is Genetic Testing Right For You?

If you’re wondering whether or not genetic testing might be a good fit, we recommend that you start the conversation with your medical team. If you or a loved one has experienced developmental delays, seizures, or other unexplained health challenges, we encourage you to reach out today.

And if you’ve been tested before, it may be worth revisiting. Genetic science is advancing rapidly and newer tests can identify variants that older tests could not.
