A paternity test compares DNA markers between an alleged father and child. The right test depends on one question: do you need the result for a court, agency, or immigration office, or just for a private answer? A home kit costs $30 to $200. A legal, AABB-accredited test costs $300 to $500 and produces a result you can submit as evidence in custody, child-support, inheritance, or immigration matters. Prenatal non-invasive paternity (NIPP) runs $1,500 to $2,000.
Key Takeaways
Home vs legal: Home kit for personal answers; AABB-accredited legal test for any court, agency, or immigration use.
Cost spectrum: $30-$200 home, $300-$500 legal, $1,500-$2,000 prenatal NIPP. Insurance rarely covers any tier.
AABB accreditation: Many U.S. courts and agencies require an AABB (Association for the Advancement of Blood and Biotherapies) accredited lab for results to be accepted as evidence; the State Department requires it for citizenship and immigration DNA testing.
Accuracy: A paternity report shows a probability of paternity, not a flat accuracy number. Legal tests with proper chain of custody usually report 99.9% or higher when the alleged father is included, with the exact figure depending on who is tested and the markers used. The State Department requires at least 99.5% for citizenship cases.
Prenatal options: Cell-free fetal DNA (cffDNA) testing works from about 7 weeks and avoids the procedure-related miscarriage risk of CVS or amniocentesis; invasive sampling carries a small added risk and is usually reserved for medically indicated cases.
Types of Paternity Tests
Paternity testing splits into five practical categories. The lab science is similar across them (short tandem repeat (STR) markers are compared between samples), but who collects the samples, whether the collection is witnessed, and whether the result is admissible varies sharply.
Home (Peace-of-Mind) Tests
Home kits arrive in the mail with cheek swabs for the alleged father and child. You collect samples yourself, mail them back, and receive results online in three to eight weeks. Because no neutral party witnessed the collection, the result cannot be used in court, on a birth certificate, or in an immigration case. Kits run $30 to $200, though many retail kits charge a separate lab fee on top of the shelf price.
Legal (Court-Admissible) Tests
Legal tests use the same lab science but add witnessed sample collection, photo ID verification, and a documented chain of custody. Samples are sealed and shipped directly from the collector to the lab. Expect $300 to $500 and one to two business days of lab turnaround once all samples arrive. AABB accreditation is the standard most courts, child-support agencies, and the U.S. State Department look for.
Prenatal Non-Invasive Paternity (NIPP)
NIPP analyzes cell-free fetal DNA (cffDNA) circulating in the mother’s blood and compares it against a cheek swab from the alleged father. Peer-reviewed work in Scientific Reports (2023) confirmed that targeted fetal DNA analysis is feasible early in pregnancy, and U.S. providers typically offer NIPP from about 7 to 9 weeks of gestation onward. Because it requires only a maternal blood draw, NIPP avoids the procedure-related miscarriage risk of CVS or amniocentesis. NIPP usually costs $1,500 to $2,000 with results in seven to ten business days.
Prenatal Invasive (CVS or Amniocentesis)
Invasive prenatal testing samples one of two things: chorionic villus sampling (CVS) collects tissue from the placenta, generally between 11 and 13 weeks of pregnancy, while amniocentesis draws fetal cells from amniotic fluid, typically from 15 weeks onward. Both are prenatal diagnostic procedures used mainly to identify chromosomal or genetic conditions, not paternity on its own. Royal College of Obstetricians and Gynaecologists guidance says the additional miscarriage risk after CVS or amniocentesis performed by a skilled operator is likely below 0.5%. Pursue invasive sampling for paternity only if it is already medically indicated. For more on prenatal safety, see our guide to DNA testing while pregnant.
Discreet (Non-Standard Sample) Tests
Discreet tests work from unconventional samples: hair with the follicle attached, fingernail clippings, a used toothbrush, chewing gum, or a cigarette butt. Success rates are lower, generally 70% to 90% of submitted samples yielding usable DNA. These tests are peace-of-mind only and may raise consent and privacy issues depending on your state. They cannot be used in court.
What a Paternity Test Costs
Prices in 2026 span a $30 home kit at the drugstore to a $2,000 prenatal NIPP through a specialty lab. Insurance rarely covers any tier, but some state child-support enforcement agencies subsidize legal testing when a case involves public assistance.
| Test Type | Typical Cost | Turnaround | Court-Admissible |
|---|---|---|---|
| Home (peace-of-mind) | $30-$200 | 3-8 weeks | No |
| Legal / AABB-accredited | $300-$500 | 1-2 business days after lab receipt | Yes |
| Prenatal NIPP | $1,500-$2,000 | 7-10 business days | Provider-dependent |
| Prenatal invasive (CVS / amnio) | $1,000-$3,000+ | 1-3 weeks | Possible if AABB chain of custody |
| Discreet samples | $200-$500 + lab fee | 1-3 weeks | No |
Retail kits often split costs into a kit price and a separate lab-processing fee. Always check whether the listed price includes lab analysis before buying. For a broader comparison across genetic services, see our guide to genetic testing costs.
Where to Get a Paternity Test
A handful of labs handle most U.S. paternity testing. The shortlist below covers the price spectrum, with AABB accreditation verified against AABB’s accredited relationship-testing facility directory. Pricing is from each provider’s published product pages as of May 2026 and subject to change.
DDC (DNA Diagnostics Center)
DDC is one of the largest U.S. paternity-testing labs and appears in AABB’s accredited relationship-testing facility directory. It offers home peace-of-mind kits, legal/court-admissible testing with witnessed collection, and prenatal NIPP. DDC sells direct and processes samples for several retail brands. It also handles multi-party testing, useful when the alleged father isn’t available and a grandparent or sibling test is needed.
HomeDNA
HomeDNA is DDC’s consumer brand, widely available at retail pharmacy chains and online. Its standard kit is peace-of-mind only; court use requires upgrading to DDC’s legal pathway with a witnessed collection appointment. Kits run roughly $30 to $50 on the shelf, plus a separate lab fee of around $130 for paternity analysis. Confirm the total at checkout; the shelf price is not the full price.
IDENTIGENE / HomeDNA
IDENTIGENE is now part of DDC and sells through retail as HomeDNA Paternity (formerly IDENTIGENE) at Walmart, Walgreens, CVS, and other major retailers. The over-the-counter kit is peace-of-mind only; if you need a result a court will accept, book DDC’s separate legal pathway with witnessed collection. The retail kit costs about $30, with a separate lab-processing fee of roughly $130 paid when you mail samples in.
EasyDNA
EasyDNA operates internationally and offers home, legal, and prenatal paternity testing through partner laboratories. U.S. legal-test orders are processed through an AABB-accredited partner lab; confirm the accreditation of the specific lab handling your sample at order time, because EasyDNA’s network shifts over time. Pricing tracks the broader market: home from around $100 to $150, legal from around $300 to $400, NIPP from around $1,500.
Labcorp
Labcorp DNA is a separate operator from IDENTIGENE/HomeDNA and appears in AABB’s accredited facility directory. It sells both at-home and legal paternity testing directly to consumers, with published starting prices around $210 for at-home and $525 for legal testing as of May 2026. Attorneys, courts, and child-support agencies can also coordinate Labcorp cases on a client’s behalf, and pricing there may differ from the direct-consumer rates.
AABB Accreditation Is the Gatekeeper
For a paternity result to function as legal evidence, the laboratory that ran it should be AABB-accredited for relationship testing. AABB (formerly the American Association of Blood Banks, now the Association for the Advancement of Blood and Biotherapies) maintains a public directory of accredited relationship-testing facilities. The U.S. Department of State requires AABB-accredited labs for citizenship and immigration DNA testing. Many state courts and child-support agencies use the same standard, though the specific rule varies by jurisdiction.
Always cross-check a lab against the AABB directory before paying for a legal test. A provider that markets itself as “AABB compliant” is not the same as a provider that appears in the accredited-facility list.
How Labs Verify Accuracy
Multiple genetic markers: Labs analyze a panel of STR loci; the industry baseline is around 16 markers, and many providers test 21 or more per sample.
Dual analysis: Independent technicians run each sample and check each other’s work.
Blind controls: Known samples are mixed into the workflow to catch errors.
Statistical probability: Every report lists a probability of paternity, not a flat accuracy number. Legal tests with proper chain of custody usually report 99.9% or higher when the alleged father is included; the exact figure depends on the tested parties and the markers used. The State Department requires at least 99.5% for citizenship cases. A 0% probability means the alleged father is excluded.
Chain of Custody Makes a Test Legal
Chain of custody is the documented record of every person who handles a sample, from collection through lab analysis to result delivery. It is the mechanism that makes a legal paternity result admissible in court, not the lab science itself. A test with an unbroken chain cannot easily be challenged on the grounds that samples were switched or contaminated.
The legal testing process follows five steps:
Book with an AABB-accredited lab: Call directly, or have your attorney or child-support agency arrange it. Confirm accreditation against the AABB facility directory before scheduling.
Schedule appointments at approved collection sites: Each participant (child, alleged father, and in some cases the mother) visits a clinic, lab, or pharmacy that the accredited lab has authorized.
A neutral collector witnesses cheek-swab collection: The collector photographs all parties, verifies photo ID, and documents the procedure on chain-of-custody forms.
Samples are sealed in tamper-evident packaging and shipped directly to the lab: No participant handles the packaged samples after collection; the collector ships directly.
The lab delivers certified results: Results go directly to the requesting party; the report is signed by the lab director and lists the probability of paternity.
| Chain Step | What Happens | Why It Matters |
|---|---|---|
| Collection | A trained, neutral technician swabs all parties and documents the encounter | Confirms the right people were tested |
| ID verification | Photo ID checked and on-site photos taken | Links each person’s name to their DNA sample |
| Sealing | Samples placed in tamper-evident envelopes | Makes any subsequent disturbance visible |
| Direct shipping | Collector ships straight to the lab | Eliminates untracked handling between collection and analysis |
| Direct result delivery | Lab sends results to the requesting court, agency, or attorney | Closes the loop on tampering |
For immigration and citizenship DNA testing, the State Department requires this protocol exactly: AABB-accredited labs, witnessed collection, and direct lab-to-government result delivery.
How Non-Invasive Prenatal Paternity (NIPP) Works
NIPP relies on cell-free fetal DNA (cffDNA) (small DNA fragments shed by the placenta that circulate in the mother’s bloodstream by the late first trimester). A standard maternal blood draw collects the plasma. The lab analyzes the cell-free DNA in that plasma, identifying fetal and placental markers mixed within the maternal DNA, then compares those markers against a cheek swab from the alleged father. A 2023 study in Scientific Reports demonstrated reliable targeted-fetal-DNA analysis early in pregnancy, and most U.S. providers offer NIPP from around 7 to 9 weeks of gestation onward.
NIPP avoids the procedure-related miscarriage risk of CVS or amniocentesis because it requires only a maternal blood draw. The higher-throughput lab workflow drives the $1,500 to $2,000 price tag. If you might need the result in court, verify with the provider whether the specific NIPP product runs through an AABB-accredited workflow.
Sample Types Labs Accept
Buccal (cheek) swabs are the standard for both home and legal paternity testing, fast, painless, and reliable for STR analysis. Labs can also work from:
Whole blood: Used when a participant is already having a draw for other reasons; common for newborns and prenatal NIPP.
Umbilical cord blood: Sometimes collected at birth for postnatal confirmation.
Discreet samples: Hair with follicle, fingernail clippings, toothbrushes, gum, cigarette butts. Lower extraction success and not legal-test eligible.
Cheek swabs are safe even for newborns, which is why labs default to them. A blood draw is rarely required for paternity alone.
How to Choose Your Test
Run through these questions to land on the right test:
Will the result be used by a court, child-support agency, or immigration officer? → AABB-accredited legal test. Pay the $300 to $500 once rather than redoing it.
Do you need proof for a U.S. citizenship or passport application? → AABB-accredited legal test; the State Department requires direct result transmission from the lab.
Are you pregnant and need an answer before delivery? → NIPP from about 7 to 9 weeks, $1,500 to $2,000. Reserve invasive prenatal testing for cases where it’s already medically indicated.
Do you only want personal answers and no paperwork? → Home peace-of-mind kit, $30 to $200.
If the situation might end up in court, default to the legal test from the start. Resampling adds time, fees, and emotional cost. When the alleged father isn’t available, related tests can fill the gap: see how a grandparent DNA test or a half-sibling DNA test can support a paternity case.
When Courts and Agencies Order Testing
Several situations commonly call for a legal paternity test:
Child support or custody disputes
Birth-certificate updates to add or correct a father’s name
Inheritance or probate proceedings
U.S. immigration and visa applications
U.S. citizenship and passport cases through the State Department
In each, judges and officers look for AABB-accredited labs and a documented chain of custody. The State Department always requires both. To understand what evidence courts accept, see how labs prove paternity or maternity.
Common Questions
How much does a paternity test cost in 2026?
Home peace-of-mind kits cost $30 to $200, including any separate lab fee. Legal AABB-accredited tests cost $300 to $500. Prenatal NIPP costs $1,500 to $2,000. Discreet samples and invasive prenatal procedures vary. Insurance rarely covers paternity testing.
Are home paternity tests accurate?
Home kits from reputable labs report 99.9% or higher probability of paternity when samples are collected properly. The limitation is not the technology; it is chain of custody. Without a neutral collector, results cannot be used in court even when the DNA analysis itself is correct.
Can you do a paternity test while pregnant?
Yes. NIPP analyzes cell-free fetal DNA from a maternal blood draw and works from about 7 to 9 weeks of pregnancy onward, avoiding the procedure-related miscarriage risk of CVS or amniocentesis. Invasive options exist but are usually reserved for medically indicated cases.
Is a CVS or Walgreens paternity test legal?
The retail kit itself is peace-of-mind only. Brands sold at drugstores, including HomeDNA Paternity (formerly IDENTIGENE) through DDC and Labcorp’s at-home kit, also offer separate, witnessed legal-test pathways. If you need court use, book the legal pathway directly with the lab.
How long does a paternity test take?
A legal test typically returns results in one to two business days after the lab receives all samples. Home kits take three to eight weeks. NIPP takes seven to ten business days. Add shipping and appointment time to each.
Does insurance cover paternity testing?
Standard health insurance does not cover paternity testing. Some state child-support enforcement agencies subsidize legal tests when paternity is being established as part of a public-assistance case.
What This Means for You
Pick the test that matches your decision, not the cheapest one. A $40 home kit answers a private question. A $400 AABB-accredited legal test produces a result a court will accept. A $1,800 NIPP can give a pregnant parent an answer around 9 weeks without the procedure-related miscarriage risk of CVS or amniocentesis. Most regret comes from running the wrong test first and paying twice, so decide whether the result needs to leave your kitchen before you order anything.
