What Is Genetic Testing — And What Can It Tell You About Your Child?
Genetic testing looks at your child's DNA to identify changes that may affect their health. Here's what it can — and can't — tell you, in plain language.
As a parent, you want the best for your child. If you’re considering genetic testing — or just trying to understand what it actually means — you’re not alone. Genetic testing is becoming more accessible to families every year, but the language around it can feel unfamiliar. This article walks you through the basics, in plain terms.
What is DNA, and why does it matter?
Every cell in your child’s body contains DNA — a kind of biological instruction book that tells the body how to grow, develop, and function. DNA is made up of genes, and each gene carries information about a specific trait or biological process.
Sometimes, a gene contains a change — called a variant — that affects how it works. Some variants are harmless. Others are linked to an increased risk for certain health conditions, or may even cause a condition directly. Genetic testing is the process of looking at your child’s DNA to identify these variants.
What can genetic testing tell you?
Depending on the type of test, genetic testing for children may help:
- Explain medical symptoms your child is already experiencing
- Identify an increased risk for certain conditions, even before symptoms appear
- Guide medical care and treatment by giving your child’s care team more precise information
- Provide information relevant to other family members, since genetic variants can run in families
For healthy-appearing children, testing offers the opportunity for early awareness — knowing about a potential risk before it becomes a problem, so that monitoring or preventive steps can begin sooner.
What genetic testing cannot tell you
It’s equally important to understand what genetic testing doesn’t do.
A genetic test can identify changes in DNA — but it cannot, on its own, confirm a diagnosis. A diagnosis requires clinical evaluation: a conversation with a medical provider who considers genetic findings alongside your child’s symptoms, history, and physical examination.
A positive result — meaning a variant was found — is not a verdict. It’s information. What that information means for your child specifically depends on many factors, and it’s something you’ll work through with your child’s care team and, at GeneSprout, with our genetic counselors and condition navigation team.
DNA is not destiny
Perhaps the most important thing to understand about genetic testing is this: a change in DNA may help explain why something happens — but it does not define who your child is, or what their life will look like.
Genes are one part of a much larger picture. Many children with genetic variants live full, healthy lives, particularly when their condition is identified early and managed proactively. Knowledge is not a sentence — it’s a tool.
What comes next
If you’re considering genetic testing for your child, the next step is understanding which type of test is right for your family. GeneSprout offers whole exome and whole genome sequencing — two approaches that differ in how much of your child’s DNA they examine. You can learn more about the difference on our Our Tests page.
Whatever you decide, the goal is the same: giving your child the best possible start, with the clearest possible picture of their health.
