Answer first: a postnatal paternity test cost usually depends less on the DNA technology and more on how the sample is collected. Personal at-home paternity tests commonly advertise prices from about $89 to $210, although some retail kits require a separate lab fee. Legal paternity tests commonly start around $279 to $525 or more because they require identity verification, witnessed collection, chain-of-custody paperwork, and a court- or agency-ready report.
If you only need private information, a home test may be the lowest-cost option. If the result may be used for child support, custody, a birth certificate, Social Security, inheritance, immigration, or a court filing, paying more for a legal test at the beginning is usually more practical than buying a home kit and later repeating the test legally.
Quick Take
- Lowest advertised home prices: AlphaBiolabs lists an at-home paternity test from $89, AffinityDNA lists a home test at $119, and Labcorp DNA lists at-home paternity testing from $210.
- Retail-kit pricing can be misleading: HomeDNA says its kit is purchased through retailers and requires an additional $139 lab fee when registering.
- Legal testing costs more: AlphaBiolabs lists legal DNA testing from $279, AffinityDNA lists legal paternity testing at $299, and Labcorp DNA lists legal paternity testing from $525.
- Legal admissibility is the deciding factor: at-home results are generally not court-admissible because the lab cannot independently verify who collected each sample.
- Turnaround starts after samples arrive: advertised 2-, 3-, or 5-business-day timelines usually do not include mailing time, appointment scheduling, recollection, or rush-upgrade delays.
Home vs legal paternity test cost comparison
| Cost factor | Home paternity test | Legal paternity test |
|---|---|---|
| Typical use | Personal knowledge or family information | Court, child support, custody, birth certificate, estate, agency, or immigration matters |
| Typical advertised postnatal price | About $89–$210, depending on provider and lab-fee structure | Often starts around $279–$525 or more |
| Collection | Self-collected cheek swabs at home | Cheek swabs collected or witnessed by an independent collector |
| Lab fee | May be included, or may be charged separately for retail kits | Usually included in quoted legal-test pricing, but collection fees may be separate with some providers |
| Shipping | Outbound kit shipping may be included; return shipping may be prepaid, standard mail, or customer-paid depending on provider | Provider or collector coordinates kit handling; international or special shipping may add cost |
| Turnaround | Commonly 2–5 business days after the lab receives all samples | Commonly 2–5 business days after the lab receives all properly documented samples |
| Legal admissibility | No, generally personal-use only | Designed for legal or official use when chain-of-custody rules are followed |
| Best fit | You want a private answer and do not expect to use the result officially | There is any chance the result will be needed by a court, agency, school, insurer, benefits office, or immigration authority |
Current provider cost examples
Pricing changes frequently, and the best comparison is the total amount you must pay for the people being tested, the lab analysis, routine collection, shipping, and any required paperwork. These examples focus on postnatal paternity testing, not prenatal paternity testing.
Labcorp DNA
Labcorp DNA lists paternity testing for both personal and legal purposes. Its paternity page lists at-home testing from $210 and legal paternity testing from $525. Labcorp describes the common legal specimen as a buccal, or cheek, swab and says legal testing emphasizes chain of custody so the sample can be valid evidence in a legal setting. For legal tests, Labcorp says a representative contacts the buyer to schedule specimen collection after order confirmation and payment.
Cost context: Labcorp’s listed legal price is higher than many online home-test offers, but the price reflects a legal workflow rather than self-collection. The standard collection pathway is part of the legal ordering process shown at checkout; confirm current checkout pricing before ordering, especially if multiple children, multiple alleged fathers, or nonstandard samples are involved.
AlphaBiolabs
AlphaBiolabs USA lists an at-home paternity DNA test from $89. The company states that this price includes the test kit, lab fees, and testing for one potential father and one child. AlphaBiolabs says USPS First Class Mail delivery of the kit is included, with optional upgrades to Priority Mail or Priority Mail Express for an added charge; return shipping is by the customer’s preferred shipping method. The company lists results by password-protected email in 3 business days after samples are received.
For legal DNA testing, AlphaBiolabs lists prices from $279. Its legal page says the lab-analysis/reporting price is included, but sample collection costs are additional. AlphaBiolabs also notes that its legal DNA test cannot be used for immigration purposes, so a separate immigration-specific test may be needed for visa or consular cases.
AffinityDNA
AffinityDNA lists a home DNA paternity test at $119 for an alleged father and child, with no charge for the mother’s sample and additional children or alleged fathers listed at $100 each. AffinityDNA says results are generally available in 3–5 business days from receipt of samples at the laboratory, plus transit time. It also states that it cannot ship home paternity tests to New York residents.
For legal paternity testing, AffinityDNA lists $299 with results in 3–5 business days after sample receipt. Its legal page explains that participants must prove identity, use an independent sampler, and have samples sealed and documented before shipment to the lab.
HomeDNA
HomeDNA Paternity, formerly IDENTIGENE and associated with DNA Diagnostics Center, is sold through retailers rather than as a standard direct online checkout. The key cost detail is that the retail kit is not the whole cost: HomeDNA says an additional $139 lab fee is required when registering the kit. Its page also says the kit is for one child, one possible father, and the biological mother if included; the mother’s participation is optional but recommended.
Cost context: For HomeDNA, compare the retail shelf or online price plus the required $139 lab fee. HomeDNA says results are generally posted two business days after samples arrive at the lab, with 1-day and same-day results available for an additional fee. The provider also states that the kit is not for New York residents and that New York requires a different process with doctor or lawyer authorization and witnessed collection.
DDC / DNA Diagnostics Center
DDC offers home paternity testing and says results are available in 1–2 business days once all samples arrive at the lab. DDC’s public help content says home tests are not appropriate for child support, custody, or other legal reasons because courts require a strict chain-of-custody process. For legal testing, DDC states that its process includes government ID verification, neutral third-party collection, tamper-taped packaging, and sample inspection on receipt.
Cost context: DDC’s direct pages emphasize phone consultation and do not consistently publish one simple postnatal legal-test price for every case. If considering DDC directly, ask for a written total covering the base test, each participant, collection-site fees, shipping, rush reporting, and any special samples. HomeDNA retail kits are connected to DDC but have their own retail-kit plus lab-fee structure.
Lab Tech Insight: the DNA test may be similar, but the paperwork is not
For many providers, the laboratory method used for a home paternity test and a legal paternity test is similar: DNA is collected, a profile is generated, and the child’s genetic markers are compared with the alleged father’s. The cost difference is largely the controlled process around the specimen. Legal testing pays for documented identity, witnessed collection, tamper-resistant handling, and a report that can be defended as belonging to the people named on it.
Why legal paternity testing costs more
A legal paternity test is not just a more expensive home kit. It is a different specimen-control process. The Association for the Advancement of Blood & Biotherapies (AABB) notes that relationship-testing accreditation is voluntary in the United States, but many state laws require AABB accreditation for reports used in legal proceedings. AABB describes relationship-testing activities as including sample collection, consent, identification, sampling, chain-of-custody documentation, secure transport, testing, verification, and reporting.
That process matters because a court or agency is not only asking whether the DNA profiles match. It is asking whether the samples were collected from the correct people, whether anyone could have switched or contaminated them, whether the collector was independent, and whether the laboratory can document every step from collection to reporting.
For immigration cases, the rules can be even stricter. The U.S. Department of State says DNA testing may be suggested when credible documentary proof is unavailable, that costs are paid by the petitioner or beneficiary, and that paternity or maternity results must report a 99.5% or greater degree of certainty to support a biological relationship in visa cases. The State Department also warns that petitioners should use AABB-accredited laboratories and should not directly receive test kits for themselves or beneficiaries in the immigration process.
What is included in the price?
When comparing paternity test cost, separate these line items:
- Kit price: the swabs, envelopes, instructions, and packaging. Retail kits may charge this separately from the lab fee.
- Lab fee: DNA extraction, marker analysis, interpretation, review, and report generation. Some companies include this in the advertised price; others charge it at registration.
- Collection fee: usually not needed for a home kit, but often relevant for legal tests. Some legal providers include routine collection in the ordering process; others state that collection costs are additional.
- Shipping: outbound kit shipping, return shipping, courier upgrades, international shipping, and embassy/consulate handling can all change the total.
- Rush reporting: faster results may cost more. Read the fine print: rush timing usually begins only after all usable samples reach the lab.
- Additional people: a base price may cover one alleged father and one child. Testing the mother, another child, or another alleged father may be free with some providers and extra with others.
- Special samples: toothbrushes, hair, nail clippings, deceased-person samples, or prenatal specimens are different test types and can cost much more than routine cheek swabs.
Specimen type and preparation
Most postnatal paternity tests use buccal swabs. A buccal swab is rubbed inside the cheek to collect cells; it is not a blood draw. The U.S. Department of State describes cheek swabs as preferred for DNA relationship testing because they are easier to collect, noninvasive, painless, and easier to ship than blood samples.
Preparation is simple but important:
- Follow the kit instructions exactly.
- Avoid eating, drinking, smoking, chewing gum, or brushing teeth shortly before collection if the kit instructions say to wait.
- Label each sample envelope carefully.
- Let swabs dry if instructed before sealing them.
- Use the correct envelope for each participant.
- For legal tests, bring required identification and follow the collector’s directions; do not open or collect the kit yourself unless instructed.
For newborns, cheek swabs are commonly used, but the mouth should be free of formula, breast milk, amniotic fluid, or other material that could interfere with collection. If a newborn was just delivered, ask the testing provider when collection can be performed cleanly and appropriately.
How to interpret paternity test results
Paternity results usually report one of two practical conclusions: the tested man is excluded as the biological father, or he is not excluded and the report gives a probability of paternity. “Not excluded” does not mean the lab tested every possible man in the world. It means the tested man’s DNA profile is consistent with being the biological father at the statistical level reported.
A strong inclusion result is often reported at 99.9%, 99.99%, or higher depending on the case, the number of genetic markers tested, population assumptions, and whether the mother is included. An exclusion usually means the tested man and child do not share the expected parent-child genetic pattern at multiple markers.
Including the biological mother is often optional, but it can make the analysis stronger because the lab can identify which child markers came from the mother and focus on the markers that must have come from the biological father. Motherless testing can still be highly informative, but close biological relatives, mutations, limited markers, missing samples, or poor sample quality may complicate interpretation.
Limitations and situations that can change the cost
Paternity testing is powerful relationship testing, but it is not the same as a diagnostic medical genetic test. It does not screen a child for genetic disease, determine ancestry percentages, or evaluate health risk. It answers a specific biological relationship question based on the samples submitted.
Several factors can change cost or require a different test:
- Potential fathers are close relatives: if two possible fathers are brothers, father and son, or otherwise closely related, tell the lab before ordering. More markers or additional relatives may be needed.
- The alleged father is unavailable: grandparentage, sibling, avuncular, or lineage tests may help, but they are not the same as direct paternity testing and often cost more.
- The result may be contested: choose legal testing from the start if there is any chance of court or agency use.
- New York restrictions apply: New York has special rules for parentage testing. New York State court information notes that court-ordered DNA testing is done at a laboratory and results are sent directly to the court. New York Department of Health materials also emphasize chain-of-custody and court-admissibility standards for paternity testing under a New York permit.
- Immigration is involved: use an immigration-specific process, not a home kit or ordinary legal test, unless the agency or consular instructions explicitly allow it.
- Privacy concerns matter: DNA data are sensitive. The Federal Trade Commission advises genetic-testing companies to clearly explain how genetic information and physical samples are used, shared, retained, or deleted. Consumers should read privacy and sample-retention policies before ordering.
How to choose the right paternity test
Start with the purpose of the result, not the lowest advertised price.
| If your situation is… | Usually consider… | Why |
|---|---|---|
| You only want private information | Home paternity test | Lowest cost and convenient cheek-swab collection |
| You may need the result for court later | Legal paternity test now | A home result generally cannot be converted into a legal result after self-collection |
| Child support, custody, birth certificate, benefits, or inheritance | Legal paternity test | These uses typically require chain-of-custody documentation |
| Immigration or visa case | Immigration DNA testing through an AABB-accredited process | Consular and agency procedures are specific and may reject ordinary kits |
| Alleged father unavailable | Relationship test with lab guidance | Grandparent, sibling, or other kinship tests may require different statistics and participants |
| Pregnancy before birth | Separate prenatal paternity test discussion | Noninvasive prenatal paternity testing is a different, higher-cost test type |
Before you order, ask the provider these exact questions:
- What is the total cost for the child, alleged father, and mother if included?
- Is the lab fee included, or do I pay it later?
- Is routine collection included for a legal test?
- Are shipping both ways and courier upgrades included?
- When does the turnaround clock start?
- What happens if a sample fails and must be recollected?
- Will this report be accepted for my intended legal, agency, or immigration purpose?
- Are there state restrictions where I live?
- How long are my physical sample and DNA data retained?
FAQs
How much does a paternity test cost?
For a postnatal paternity test, personal at-home testing commonly costs about $89 to $210 before optional shipping or rush upgrades, while legal paternity testing commonly starts around $279 to $525 or more depending on the provider, number of people tested, and collection requirements. Retail kits may also require a separate lab fee.
Why is a legal paternity test more expensive than a home test?
Legal testing costs more because the samples must be collected under documented chain-of-custody conditions. That usually includes identity verification, an independent collector, tamper-resistant packaging, documented transfer to the laboratory, and a report designed for court or agency use.
Can a home paternity test be used in court?
No. Home paternity tests are generally for personal knowledge only. Courts and agencies usually require a legal test with chain of custody because home collection does not independently verify who provided each sample.
Are lab fees included in paternity test prices?
It depends on the provider. Some providers include the kit and lab analysis in the advertised price. Retail kits may be inexpensive at the store but require a mandatory lab fee when the kit is registered. Always compare the total cost, not just the kit price.
Does health insurance cover paternity testing?
Usually no. Paternity testing is generally treated as non-medical relationship testing, not a diagnostic medical test, so health insurance and Medicaid typically do not cover voluntary paternity testing.
What sample is used for a paternity test?
Most postnatal paternity tests use cheek swabs collected from the child and alleged father. The mother’s sample is often optional but can strengthen the analysis in some situations. Legal tests use similar specimens but require witnessed collection and chain-of-custody documentation.
Practical next steps
If you are comparing paternity test cost, first decide whether the result is for personal knowledge or for official use. Then compare the full consumer price: advertised test price, lab fee, collection fee, shipping, extra participants, and rush options. If the result might affect legal rights, benefits, custody, support, immigration, or a birth record, contact the court, agency, attorney, or testing provider before collecting any sample at home. Choosing the correct test type at the start can prevent paying twice for the same question.
