Answer first: noninvasive prenatal paternity testing usually costs far more than a standard paternity test after birth. In current public pricing reviewed for this article, advertised noninvasive prenatal paternity test prices ranged from about $675 to $1,395 where a price was posted, while some major providers require a phone quote instead of showing a single checkout price. The real amount you pay can change with blood collection, legal chain-of-custody collection, shipping speed, extra alleged fathers, alternate sample testing, and state restrictions.
A prenatal paternity test is not the same thing as routine prenatal genetic screening. It is a relationship test designed to determine whether a tested man is or is not consistent with being the biological father of the fetus. Most current consumer-facing prenatal paternity tests are noninvasive prenatal paternity tests, often abbreviated NIPP or NIPPT. They usually require a blood draw from the pregnant person and a cheek swab from the alleged father. The laboratory analyzes cell-free fetal DNA in maternal blood and compares fetal markers with the alleged father’s DNA profile. Early research in The New England Journal of Medicine described noninvasive paternity testing using cell-free fetal DNA in maternal blood, and later studies have evaluated SNP- and sequencing-based methods for this purpose.

Quick Take
- Typical cost: expect several hundred dollars to more than $1,000 for noninvasive prenatal paternity testing; it is much more expensive than most after-birth home paternity kits.
- Timing: many providers advertise testing from about 7 to 9 weeks of pregnancy, but timing rules vary by company and how gestational age is counted.
- Specimens: the standard setup is maternal blood plus a cheek swab from the alleged father; some providers also require or recommend a maternal cheek swab.
- Legal use: a peace-of-mind kit is not automatically court-admissible. Legal use usually requires witnessed collection, identity verification, and chain-of-custody paperwork.
- Not medical diagnosis: prenatal paternity testing determines a biological relationship question. It does not screen for Down syndrome, diagnose fetal conditions, replace prenatal care, or establish legal parentage by itself.
What a noninvasive prenatal paternity test does
During pregnancy, small fragments of DNA from the placenta circulate in the pregnant person’s bloodstream along with a much larger amount of maternal DNA. Clinical prenatal screening uses this cell-free DNA concept for chromosome-risk screening, and paternity laboratories use a related high-level principle for relationship testing. A paternity laboratory looks at many DNA markers, often single nucleotide polymorphisms, or SNPs, and uses statistical analysis to evaluate whether the fetal DNA pattern is consistent with the tested man being the biological father.
This is why prenatal paternity testing is technically different from a standard after-birth paternity test. After birth, a lab can test cheek swabs from the child and alleged father directly. During pregnancy, the fetal DNA signal is mixed into maternal plasma, is fragmented, and may be present at a relatively low fraction, especially early in pregnancy. Published method studies describe the use of SNP microarray, targeted sequencing, next-generation sequencing, and bioinformatics to separate a fetal relationship signal from maternal background DNA.
Prenatal paternity test cost: current provider examples
Prices change often, and some companies do not publish a single price because the case setup may differ. The table below compares public price signals and ordering facts found on provider pages reviewed for this article. It is not a ranking, and it should not be read as a recommendation for any individual situation.
| Provider | Current public price signal | Specimens and timing | Important cost and availability notes |
|---|---|---|---|
| AlphaBiolabs USA | $675 plus free shipping for a noninvasive prenatal paternity test including one potential father. | Advertises testing from 7 weeks. Requires maternal blood plus cheek swabs from the mother and potential father. | States the price includes the kit, USPS Priority Mail to the customer, testing for one potential father, lab fees, and a digital report. Maternal blood must be collected by a trained practitioner; AlphaBiolabs lists a professional collection option for +$99. The site states DNA tests are not offered to New York State residents. |
| DDC / DNA Diagnostics Center | No single checkout price was posted on the reviewed prenatal paternity page; the page directs users to call for consultation and payment options. | Advertises testing as early as 7 weeks. Requires maternal blood and an alleged-father cheek swab, with some non-legal alternate sample options. | Offers legal and non-legal pathways. DDC states legal prenatal testing uses strict chain of custody; self-collected alleged-father samples are not court-admissible because identity cannot be verified. The page advertises results in as little as 3 business days after sample processing milestones, but the final timeline depends on collection and shipping. |
| HomePaternity | Listed a noninvasive prenatal paternity test at $795 sale price, reduced from $995, on the reviewed product page. | Advertises testing from 7 weeks. Includes maternal blood draw and possible-father cheek swab. | Lists 3,000+ nationwide collection locations or a ship-to-home path where the pregnant person finds a blood collector. The page says ship-to-home is not available to New York residents and that the test cannot be used for twins or multiples, IVF pregnancies, or close biological relationships between possible fathers. |
| homeDNAdirect | $1,195 starting price. | Advertises testing from 9 weeks of pregnancy, described as 7 weeks past conception. Requires maternal blood and alleged-father saliva/cheek sample. | Lists standard results in 5 to 7 working days from receipt of samples and an optional gender upgrade for $175. The page lists several exclusions, including IVF, twin or multiple pregnancy, close blood relatives as possible fathers, recent transfusion, transplant, stem-cell therapy, cancer, and pre-eclampsia. |
| AffinityDNA | Public pages were inconsistent: the paternity overview listed prenatal paternity testing at $1,395, while the specific prenatal page was marked “Available Soon” and stated “from only $745.” | The specific page describes testing from 7 weeks using maternal blood and potential-father cheek swab. | Because the page was marked available soon and pricing differed across AffinityDNA pages, confirm availability, total price, legal option, and collection fees directly before relying on the listing. |
| Labcorp DNA and HomeDNA | No current prenatal paternity product price was found on the reviewed public pages. | Labcorp DNA lists postnatal paternity testing and other relationship tests; Labcorp’s clinical genetics pages discuss prenatal cfDNAIPT screening, which is not a paternity test. HomeDNA’s reviewed catalog listed retail postnatal paternity testing with an additional lab fee, not a prenatal paternity test. | These brands may still be relevant for after-birth paternity testing or clinical prenatal screening, but those are different services. Do not buy a postnatal kit or a clinical NIPT screen expecting it to answer prenatal paternity. |
Why prenatal paternity testing costs more than after-birth testing
The high cost is mostly about the laboratory challenge and collection logistics, not just the word “prenatal.” A postnatal home paternity kit usually compares DNA from two clear sources: a child and an alleged father. A noninvasive prenatal test must evaluate fetal DNA fragments in a maternal blood sample where most cell-free DNA is maternal. The lab may need specialized tubes, careful shipping, plasma processing, DNA extraction, high-density marker analysis, bioinformatics review, and quality checks before issuing a result.
Cost can also rise because prenatal paternity orders are often customized. A legal case may need identity verification and witnessed collection for each tested person. An alleged father in another city may need separate collection coordination. A non-standard sample, such as fingernails or a cigarette butt, may need viability testing and may not be acceptable for legal use. Extra alleged fathers, rush shipping, mobile phlebotomy, hard-copy reports, and retesting after an inadequate sample can also change the final cost.
When the test can be done
Most commercial noninvasive prenatal paternity testing starts no earlier than the first trimester, commonly around 7 to 9 weeks depending on the provider. AlphaBiolabs and DDC advertise testing from 7 weeks, HomePaternity also advertises 7 weeks, and homeDNAdirect advertises 9 weeks of pregnancy. Timing matters because early pregnancy samples can have less fetal DNA. If the fetal fraction is too low or the sample quality is poor, the lab may not be able to issue a clear report. That can mean a recollection, delayed result, or an inconclusive report depending on the provider’s policy. If pregnancy dating is uncertain, ask the provider exactly how it calculates eligibility: from the first day of the last menstrual period, from conception, or by ultrasound dating.
Specimens: what you usually have to provide
The standard specimen set is straightforward but must be handled correctly:
- Pregnant person: a blood draw, usually collected into special tubes supplied by the testing company.
- Alleged father: usually cheek swabs; some providers allow blood or alternate samples in limited non-legal cases.
- Pregnant person cheek swab: required by some providers so the lab can better separate maternal and fetal genetic contributions.
- Additional alleged fathers: may be recommended when more than one possible father exists, especially if possible fathers are related.
Do not substitute tubes, collection materials, or shipping methods unless the lab tells you to. Cell-free DNA testing is sensitive to specimen handling. A routine phlebotomy site may be able to draw blood, but it still needs the correct kit, forms, tube type, labeling, and shipping instructions from the paternity laboratory.
Legal vs peace-of-mind prenatal paternity testing
The biggest ordering decision is whether the result is only for private information or might be used for court, child support, custody, a birth certificate, inheritance, immigration, or an attorney-guided matter. For legal use, the issue is not only the DNA technology. It is whether the identity of each participant and the handling of each specimen can be documented from collection to reporting.
AABB explains that many U.S. statutes require AABB accreditation for legal relationship testing and that U.S. federal agencies require AABB-accredited DNA testing for immigration and visa applications. AABB’s current relationship-testing facility list includes DDC/DNA Diagnostics Center and Laboratory Corporation of America Holdings among accredited facilities; AABB also notes the list is current as posted and can change. DDC’s prenatal paternity page specifically distinguishes legal and non-legal testing. It states that legal prenatal testing follows strict chain of custody and that a possible father’s at-home cheek swab is not court-admissible because the lab cannot verify the sample was collected from that person. AlphaBiolabs similarly states its online peace-of-mind prenatal test cannot be used for legal purposes or court proceedings and directs legal cases to a separate legal DNA process.
How results are reported and what they do not prove
A prenatal paternity report generally gives either an exclusion or a very high probability that the tested man is not excluded as the biological father. “Excluded” means the DNA evidence is not consistent with the tested man being the biological father. “Not excluded” means the tested man’s DNA is consistent with paternity at the markers analyzed, usually with a high probability.
A result is not the same as a court order. It does not by itself establish custody, child support, immigration status, parental rights, or a birth certificate change. Those questions depend on state law, court procedure, agency rules, and the legal status of the people involved. If the result could affect a legal decision, speak with an attorney or the relevant agency before ordering so you do not pay for the wrong type of test.
Medical and laboratory limitations to understand
Noninvasive prenatal paternity testing is often marketed with very high accuracy claims, but every result depends on the specific lab method, sample integrity, fetal DNA amount, correct participant identity, and the relationship of the tested men. DDC notes that paternity probability cannot truly be reported as 100% because another man could theoretically have nearly identical DNA, especially a close relative. Some situations require special handling or may be excluded by the provider. Examples from provider pages include twins or multiples, IVF or surrogacy, possible fathers who are close biological relatives, recent transfusion, transplant, stem-cell therapy, certain maternal medical conditions, vanishing twin scenarios, or very early gestational age. These are not small-print details; they can determine whether a test can be performed and whether a result is interpretable. Also keep prenatal paternity testing separate from medical prenatal screening. ACOG describes cell-free DNA screening as a prenatal genetic screening option for chromosomal abnormalities and emphasizes that screening is not the same as diagnostic testing. The FDA has warned about false results and inappropriate interpretation of genetic noninvasive prenatal screening tests; that warning is about medical NIPSIPT screening rather than relationship testing, but it is a useful reminder that prenatal DNA tests should be interpreted in the right context.
How to compare total cost before ordering
For a commercial prenatal paternity test, compare the total amount you must pay to complete the case, not just the headline price. Before entering payment information, ask these questions:
- What is the total price for the pregnant person and one alleged father?
- Does the price include all lab fees, or is there a separate fee at registration?
- Is the maternal blood draw included, or do I need to pay a phlebotomist, clinic, or mobile collector?
- Is shipping both ways included, and what happens if the sample arrives late or is unusable?
- How much does it cost to test an additional alleged father?
- Is this a legal chain-of-custody test or a private peace-of-mind test?
- Are results available in my state, especially if I live in New York?
- What situations make the test unavailable or more complicated, such as twins, IVF, related possible fathers, or recent transfusion?
- What is the redraw or recollection policy if the fetal DNA amount is too low?
- When does the advertised turnaround time start: order date, blood draw date, lab receipt date, or acceptance of all samples?
Practical next steps
If you are considering prenatal paternity testing, start by deciding whether the result is private information or may be needed for a legal or agency purpose. Then verify gestational age, specimen requirements, total price, blood collection options, state availability, and turnaround time directly with the provider. If the pregnancy involves twins, IVF, surrogacy, close relatives as possible fathers, recent transfusion, transplant, or a complex legal situation, contact the provider before ordering and consider legal or genetic-counseling guidance as appropriate.
If cost is the main barrier and there is no urgent prenatal need, an after-birth paternity test is usually much less expensive and simpler to collect. If the result could affect court filings, child support, custody, immigration, or official parentage records, ask for a legal chain-of-custody process from the start rather than paying twice.
Frequently Asked Questions
How much does a prenatal paternity test cost?
Noninvasive prenatal paternity testing commonly costs several hundred dollars to more than $1,000. Public examples reviewed here included $675 from AlphaBiolabs USA, $795 sale pricing from HomePaternity, $1,195 from homeDNAdirect, and AffinityDNA pages that showed both an older $1,395 listing and a newer page marked available soon from $745. DDC offers prenatal paternity testing but did not publish a single checkout price on the reviewed page.
Why is prenatal paternity testing so expensive?
It is expensive because the lab is not testing a baby’s direct cheek swab. It is analyzing fetal DNA fragments mixed into maternal blood, comparing many markers with the alleged father’s DNA, and applying specialized quality controls. Blood collection, legal chain of custody, shipping, extra alleged fathers, and rush options can add more cost.
When can a prenatal paternity test be done?
Many providers advertise testing from about 7 to 9 weeks of pregnancy, depending on the company and how pregnancy dating is calculated. Testing too early can increase the chance that fetal DNA is too low for a clear result.
What samples are needed?
Most tests require a blood sample from the pregnant person and a cheek swab from the alleged father. Some providers also collect a cheek swab from the pregnant person. Some non-legal tests may accept alternate alleged-father samples, but these may cost more, fail viability testing, or be unacceptable for legal use.
Can a prenatal paternity test be used in court?
Only if it is ordered and collected as a legal chain-of-custody test that meets the court or agency’s requirements. A private self-collected kit should not be assumed to be court-admissible.
Is prenatal paternity testing the same as NIPT?
No. Prenatal paternity testing is a relationship test. NIPT or NIPS is a prenatal screening test for certain chromosomal conditions. They use related cell-free DNA concepts but answer different questions and produce different types of reports.
Can the test be wrong?
High-quality laboratories use extensive marker testing and quality checks, but no test should be treated as magic. Wrong participant identity, poor collection, low fetal DNA, close biological relationships between possible fathers, unusual pregnancy situations, or using the wrong test type for a legal purpose can undermine the usefulness of a result. Ask the lab how it handles inconclusive results, recollection, and related alleged fathers before ordering.
Is it safer than amniocentesis or CVS for paternity?
For paternity purposes, noninvasive testing avoids sampling amniotic fluid or placental tissue and instead uses a maternal blood draw. Invasive procedures such as amniocentesis and CVS are medical diagnostic procedures ordered for clinical reasons, not casual relationship testing. Discuss any invasive prenatal procedure with an OB-GYN or maternal-fetal medicine specialist.
