You can get your DNA tested at home with a mail-in kit, at a doctor’s office through a clinical lab, or at one of thousands of walk-in collection centers run by major lab companies. The right option depends on what you want to learn: your ancestry, your health risks, or whether you carry genes that could affect your children.
At-Home Consumer Kits
The fastest way to get started is ordering a direct-to-consumer kit online. Companies like 23andMe and AncestryDNA ship a saliva collection tube to your door. You spit into it, seal it, and mail it back. Results arrive in 2 to 8 weeks, depending on the type of test and how busy the lab is. That clock starts when the lab receives your sample, not when you drop it in the mail.
These kits use a technology called SNP genotyping, which reads hundreds of thousands of specific markers across your genome. It’s enough to estimate your ethnic background, connect you with genetic relatives, and flag certain health-related variants. Pricing ranges from about $49 for basic ancestry reports to $200 or more for kits that bundle ancestry with health information. 23andMe’s health reports hold FDA clearance for a handful of specific conditions, including selected variants linked to breast cancer, ovarian cancer, colorectal cancer, and hereditary prostate cancer. Those reports cover only a small number of known variants for each condition, so a “clear” result doesn’t rule out your risk entirely.
Consumer kits are a reasonable starting point if you’re curious about your heritage or want a general snapshot of your genetics. They are not a substitute for medical-grade testing if you have a family history of a specific disease or your doctor has flagged a concern.
Clinical Testing Through Your Doctor
If you have a medical reason for genetic testing, your doctor or a specialist can order it through a clinical laboratory. This is the route for targeted questions: Do you carry a mutation that causes cystic fibrosis? Is there a genetic explanation for your family’s history of early-onset cancer? Would a specific medication work better or worse for you based on your genes?
Quest Diagnostics, one of the largest lab networks in the U.S., offers genetic tests across cardiology, hereditary cancer, pregnancy and fertility, pharmacogenomics (how your body processes certain drugs), and more. They operate over 2,200 patient service centers nationwide where you can have your specimen collected in person. Labcorp provides a similar range of services. In both cases, a clinician orders the test, and the lab handles the analysis and returns results to your provider.
Clinical tests are more focused than consumer kits. Instead of scanning your whole genome broadly, they zero in on specific genes or panels of genes relevant to your situation. The results come with clinical interpretation, and your doctor or a genetic counselor walks you through what they mean for your care. Processing times for health-related genetic tests typically fall between 2 and 6 weeks.
Whole Genome Sequencing
SNP genotyping reads selected markers. Whole genome sequencing reads nearly all of your DNA, giving you the most complete picture available. This used to cost thousands of dollars, but prices have dropped significantly. Several companies now offer it directly to consumers, and clinical labs like Broad Clinical Labs provide both clinical and research-grade whole genome sequencing, sometimes bundled with deeper analysis of the protein-coding regions of your genes.
Whole genome sequencing picks up rare variants that standard consumer kits miss entirely. If you’re interested in the most thorough analysis possible, or if a clinician needs to search broadly for a genetic explanation, this is the most comprehensive option. It also generates a massive raw data file you can revisit as science learns more about specific genes in the future.
Paternity and Legal DNA Tests
Paternity testing is one of the most common reasons people search for DNA testing. At-home paternity kits are available online and at many pharmacies. You collect cheek swabs from the individuals involved, mail them to the lab, and receive results in about 1 to 3 weeks (with lab processing itself taking 3 to 10 business days).
There’s an important distinction here. An at-home paternity test can tell you the answer privately, but it won’t hold up in court. If you need results for a legal matter like child custody or child support, you’ll need a “legal” or “chain of custody” test. This requires sample collection at a certified facility where a trained collector verifies everyone’s identity and documents the process. Many lab companies and independent DNA testing centers offer this service at walk-in locations.
Will Insurance Cover It?
Consumer ancestry and health kits are paid out of pocket. Insurance does not cover them. Clinical genetic testing ordered by a doctor, on the other hand, may be covered if it meets your insurer’s criteria for medical necessity. Those criteria generally require that you’re showing symptoms of a condition or are at direct risk of inheriting a known mutation, the test result would change how your doctor treats you, and conventional workup hasn’t produced a definitive diagnosis.
Medicare follows a similar framework: the treating physician must order the test to help manage the patient’s care. If your testing is purely elective or exploratory, expect to pay out of pocket even with a doctor’s order. Before scheduling, call your insurer to ask whether the specific test your doctor is recommending is covered under your plan. Many genetic testing companies also offer payment plans or financial assistance programs.
Privacy Protections and Gaps
A federal law called the Genetic Information Nondiscrimination Act (GINA) makes it illegal for health insurers to use your genetic information to deny you coverage, set premiums, or make underwriting decisions. It also prevents employers with 15 or more employees from using genetic information in hiring, firing, promotions, or job assignments. Employers cannot request or require genetic testing as a condition of employment.
GINA has real limits, though. It does not cover life insurance, long-term care insurance, or disability insurance. Companies in those industries can legally ask about genetic test results and use them in their decisions. Some states have passed additional laws that fill in these gaps, but protections vary widely. The U.S. military is also exempt and can use genetic information in employment decisions. If you’re considering testing and plan to apply for life or long-term care insurance in the near future, it’s worth understanding your state’s specific protections before you test.
Each testing company also has its own privacy policy governing how your data is stored, shared, and potentially used for research. Read the consent forms carefully, especially the sections about third-party data sharing and law enforcement requests.
Working With a Genetic Counselor
Genetic counselors are trained professionals who help you understand what testing is appropriate for your situation and what your results actually mean. This is especially valuable for clinical testing, where a single variant can have very different implications depending on your family history and other risk factors. Consumer test results can also be worth reviewing with a counselor, particularly if a health report flags something concerning.
The National Society of Genetic Counselors maintains a searchable directory where you can find counselors by ZIP code, specialty, and location across the U.S. and Canada. The American Board of Genetic Counseling offers a similar directory of certified counselors worldwide. Many counselors now offer telehealth appointments, so you’re not limited to whoever is closest to you geographically. Some testing companies include access to genetic counseling as part of their service, while others charge separately or leave it to you to arrange.
