You can do a DNA test at home with a mail-in kit, at a retail pharmacy, through your doctor’s office, or at a specialized lab facility. The right option depends on what you’re trying to learn. A simple ancestry kit costs as little as $99 and arrives at your door, while a medical-grade genetic test ordered through a healthcare provider may cost nothing out of pocket with insurance.
At-Home Mail-In Kits
The most popular option for ancestry and basic health screening is a direct-to-consumer kit you order online. Companies like 23andMe and AncestryDNA ship a saliva collection tube to your home. You spit into it, seal it, and mail it back. Results typically arrive in a few weeks.
23andMe currently offers three tiers: a basic ancestry test for $99, an ancestry plus health screening package for $199, and a more comprehensive health and ancestry membership for $499. The health-focused tiers screen for things like carrier status for inherited conditions, risk variants linked to breast cancer (BRCA1 and BRCA2), Alzheimer’s risk, and lifestyle-related traits such as how your body processes caffeine or responds to certain diets. The $199 and $499 tiers renew annually at $69 and $199 respectively, though you can cancel anytime.
These kits are convenient, but they have limits. They test for a curated selection of genetic variants, not your entire genome. A result showing “no increased risk” for a condition doesn’t guarantee you won’t develop it. And ancestry estimates are based on reference populations that vary between companies, so your results from one service may differ slightly from another.
Retail Pharmacies
If you’d rather pick up a kit in person, major pharmacy chains carry them. Walgreens sells its own branded at-home DNA paternity test kit, and stores like CVS, Walmart, and Target typically stock ancestry kits from well-known brands on their shelves or websites. You still collect your sample at home and mail it to the lab yourself. There’s no in-store testing involved.
Pharmacy paternity kits are fine for personal knowledge, but they won’t hold up in court. If you need results for a legal matter like child custody or child support, you’ll need a different process entirely.
Your Doctor’s Office
For medically meaningful genetic testing, your doctor or a genetic counselor can order a clinical-grade test. This is the route to take if you have a family history of cancer, a suspected inherited condition, or if a previous consumer test flagged something concerning. Clinical tests are more thorough and more targeted than consumer kits. They’re analyzed in certified laboratories and interpreted by genetics professionals.
Major diagnostic labs like Quest Diagnostics handle a large share of physician-ordered genetic tests. Quest is in-network with more than 90% of U.S. health plans, and roughly 90% of patients who meet their insurer’s testing criteria pay nothing out of pocket. Those who do pay typically owe less than $100. Many labs also run a pre-authorization process to check your coverage before testing, so you’re not blindsided by a bill.
During a clinical genetics appointment, you’ll meet with a medical geneticist, a genetic counselor, or both. They review your personal and family medical history, explain what the test can and can’t tell you, and help you understand the results afterward. Large medical centers offer specialized genetics clinics for specific concerns: cancer risk, heart conditions, neurological disorders, reproductive planning, and pediatric genetics, among others.
Legal and Paternity Testing Facilities
If you need DNA test results that will be accepted by a court, you can’t use a home kit. Legal paternity tests require what’s called chain of custody, meaning every step of sample collection and handling is documented and witnessed. A trained collector takes your sample (usually a cheek swab) at an approved facility, verifies your identity with a photo ID, and seals the sample with tamper-evident packaging. This ensures no one could have swapped or contaminated the sample.
You can find chain-of-custody collection sites through companies like DNA Diagnostics Center, LabCorp, and various local testing facilities. Many are walk-in or appointment-based and located in medical office buildings. Courts, immigration offices, and government agencies generally require this type of verified testing. Expect to pay more than a home kit, but results are fast. Standard turnaround is a few days to two weeks, and some labs offer expedited one-day or same-day results for an extra fee.
The accuracy of paternity testing is extremely high. With standard methods, the chance of falsely identifying a biological father as unrelated is about 1 in 1,700 for a standard trio test (mother, child, alleged father). The chance of falsely identifying an unrelated man as the father is roughly 1 in 142,000. Newer testing technologies using denser genetic data push accuracy even closer to 100%.
What Your Results Can and Can’t Do
Consumer ancestry and health kits give you interesting personal information, but they aren’t medical diagnoses. If a home test flags you as a carrier for a genetic condition or shows an elevated disease risk, the recommended next step is confirmatory testing through a healthcare provider. Clinical labs use validated methods and can sequence specific genes more completely than consumer kits do.
One thing worth knowing before you test: the Genetic Information Nondiscrimination Act (GINA) protects you from discrimination by health insurers and employers based on your genetic results. Health insurers cannot use your genetic data to deny coverage, set premiums, or make underwriting decisions. Employers with 15 or more employees cannot use genetic information in hiring, firing, promotions, or job assignments. However, GINA does not cover life insurance, long-term care insurance, or disability insurance. Some states have additional laws that fill those gaps, but the federal protection has clear limits.
Ancestry tests can also surface unexpected information, like previously unknown biological relatives or ancestral origins that don’t match your family’s understanding of its history. That’s worth considering before you order a kit, especially if you or close family members might find such discoveries distressing.
Choosing the Right Option
- Curiosity about heritage or ethnicity: A consumer ancestry kit ($99 and up) is the simplest starting point. Order online or grab one at a pharmacy.
- General health and trait insights: A consumer health screening kit ($199 to $499) covers carrier status, disease risk variants, and wellness traits.
- Paternity for personal knowledge: An over-the-counter paternity kit from a pharmacy works, with results in one to two weeks after the lab receives your samples.
- Paternity for court or legal purposes: Visit an accredited collection site that maintains chain of custody. Search online for “legal paternity test near me” to find local options.
- Medical concerns or family history of disease: Ask your doctor for a referral to a genetics specialist. Insurance often covers clinical testing when there’s a medical reason for it.
