Should You Try Direct-to-Consumer Genetic Testing? What You Need to Know
Genetic testing is more accessible than ever. With kits available online and even at your local pharmacy, it’s easier than ever to explore your DNA from the comfort of home.
But as interest in direct-to-consumer (DTC) genetic testing grows, so do the question and the confusion.
In a recent All Access DNA podcast episode, genetic counselor Andy McCarty shared insights from his work in private practice, where he frequently helps patients interpret these results. Here’s what you need to know before and after you take a genetic test.
Why Are People Turning to At-Home Genetic Tests?
There’s no single reason people pursue DTC genetic testing—but a few common themes come up again and again.
1. Curiosity
For many, it starts with simple curiosity. People want to learn more about their ancestry, traits, or potential health risks.
2. Accessibility
Traditional healthcare systems can be hard to navigate. Long wait times, referral requirements, and limited access to specialists can make clinical genetic testing feel out of reach.
DTC tests, on the other hand, are easier to find and seem more simple than making an appointment.
3. Cost Concerns
Many people assume clinical genetic testing costs thousands of dollars. In reality, that’s often not the case, but the perception alone drives people toward cheaper, direct-to-consumer options. Medical genetic testing can be covered in partial or in full by insurance. And if you have questions about if you need a medical genetic testing and what may be covered- talk to a genetic counselor (findageneticcounselor.org)
4. Feeling Dismissed by the Healthcare System
Some individuals pursue testing after feeling unheard or dismissed in medical settings. For them, these tests offer a way to take control and search for answers on their own.
What Are People Hoping to Learn?
Many people, especially those dealing with chronic or unexplained symptoms, hope genetic testing will provide clarity.
They may be asking: Why do I feel this way? Is there a diagnosis that ties everything together? What should I do next?
In some cases, they’re looking for a clear answer. In others, they’re simply hoping for direction.
The Reality: It’s Not Always That Simple
Here’s where expectations and reality can diverge.
Genetic Results Are Rarely Black and White
Genetic testing doesn’t usually give a simple “yes” or “no” answer. Instead, results often fall into categories like:
Benign (not harmful)
Uncertain significance (we’re not sure what it means)
Pathogenic (disease-causing)
That gray area can be confusing and sometimes add anxiety.
More Information ≠ More Clarity
DTC tests can provide a lot of data. But without proper interpretation, that information can feel overwhelming.
For example, you might see a gene linked to a serious condition, but that doesn’t necessarily mean you have, or will develop, or that condition.
All humans have genetic variations. The key is understanding which ones matter.
Why Interpretation Matters
This is where genetic counselors play a critical role. Interpreting a result involves more than just reading a report. It includes:
Reviewing scientific data about the variant
Assessing how common it is in the population
Evaluating whether it affects how a gene functions
Comparing findings with your personal and family health history
It’s about putting the pieces together and not just looking at one result in isolation.
A Big Limitation: Accuracy and Confirmation
One of the most important takeaways is this:
Direct-to-consumer results often need to be confirmed with clinical-grade testing.
Why?
Because:
Testing methods may differ in quality
Some tests only look at a limited number of variants
Certain genetic conditions require specialized testing that DTC kits don’t include
If a result could impact medical decisions, like increased cancer risk, it’s essential to verify it through a certified clinical lab.
Common Misconceptions About Genetic Testing
❌ “If my test is negative, I’m in the clear.”
Not necessarily.
A negative result might mean:
The test didn’t look at the right genes
Science hasn’t identified your specific variant yet
There are non-genetic factors at play
❌ “If I have a gene, I’ll definitely get the condition.”
Also not true.
Genetics is about probability, not certainty.
Many genetic findings increase risk, but don’t guarantee outcomes.
❌ “Clinical testing is always expensive.”
Surprisingly, many clinical tests cost similar to, or even less than, DTC tests, depending on insurance and the type of test.
Benefits of Direct-to-Consumer Testing
Sometimes DTC testing can be helpful:
✔️ It can spark important conversations
People may learn about family history or start discussing health risks with relatives.
✔️ It can motivate action
A result—even if imperfect—may prompt someone to seek medical care or further evaluation.
✔️ It can provide a starting point
While not definitive, it can offer clues that guide next steps.
Risks to Consider Before Testing
Before you click “order,” there are a few important risks to keep in mind.
1. Data Privacy
Who owns your genetic data?
Some companies may store, share, or even sell it. Always read the fine print. Additionally, some companies may CURRENTLY promise not to share or sell data but that can easily change in the future. And if a company gets bought out by another company or entity, the current terms and conditions may no longer apply.
2. Unexpected Findings
Testing can reveal surprising information, such as:
Unexpected ancestry results
Misattributed parentage
Previously unknown family relationships
These discoveries can have emotional and personal impacts.
3. Misinterpretation
Without expert guidance, results can be misunderstood—sometimes leading to unnecessary anxiety or even inappropriate medical decisions.
What Should You Do If You Already Took a Test?
If Your Results Show Something Concerning:
Don’t panic
Talk to a genetic counselor or knowledgeable clinician
Consider confirmatory clinical testing
If Your Results Seem “Normal”:
Don’t assume everything has been ruled out
Continue routine medical care and screenings
Consider further evaluation if you have a strong personal or family history
The Bigger Picture: Genetics Is About Probability
One of the most important takeaways is this:
Genetic testing doesn’t predict your future- it informs your risk.
Your health is shaped by many factors:
Genetics
Environment
Lifestyle
Chance
Even the most advanced testing can’t provide absolute certainty.
Final Takeaway
Genetic testing is more accessible than ever—but not all tests are created equal.
If you’re considering direct-to-consumer testing, or already have results, remember:
Do your research
Be cautious with interpretation
Seek guidance from qualified professionals
Because when it comes to your DNA, understanding the results matters just as much as getting them.
