Frequently Asked Questions
Please take a moment to review our FAQ section below for quick answers to commonย questions.
Prenatal Paternity
How does a prenatal paternity test work?
The DDC Non-Invasive Prenatal Paternity Test is the most accurate non-invasive way to determine paternity before a babyโs birth. The DDC process is state-of-the-art, combining the latest in DNA SNP microarray technology and paternity-determining algorithms. The babyโs DNA is found naturally in the motherโs bloodstream. The test requires a blood sample from the mother; then with our unique processing, the babyโs DNA is isolated from the motherโs and compared to the DNA taken from the possible father. A probability of paternity is determined, and a report is then produced.
How accurate is a non-invasive prenatal paternity test?
At DDC we provide at least a 99.9% probability on prenatal paternity tests. A prenatal test is just as accurate as a postnatal test.
Why should I establish paternity while pregnant?
A main reason to establish paternity while pregnant is to determine the father of a child as early as possible. More complex reasons may include access to legal and social benefits, establishing accurate medical histories, ensuring the biological father is involved in the pregnancy, and perhaps simply to strengthen the family bond, particularly between a father and child.
Can I use the prenatal paternity test results in court?
Results from a prenatal paternity test can be used in court as long as samples were obtained using a chain-of-custody process. Non-legal testing is also an option. Not sure which is right for your unique situation? Give us a call today.
What is the earliest I can get a paternity test while pregnant?
The DDC prenatal paternity test can be performed as early as 7 weeks after conception.
How long does it take to get results for a prenatal paternity test?
Results are posted 7 business daysย after samples are received at the lab. 3-day results once samples arrive at the lab are available for an additional fee.
How will I receive my results?
For security reasons, we doย notย send a copy of your results via email. Instead, a PDF report can be downloaded from your secure online account on our website. We immediately send a notification email to the address on file as soon as the online report is ready to view. For a legal paternity test, all tested parties receive a hard-copy of the report as long as mailing addresses are given in writing.
Does a legal prenatal paternity test report have names of participants on them?
Yes, because a chain-of-custody process has been followed and the identities of participants have been independently verified. There are no names on non-legal test reports.
What do test results look like, and how do I interpret them?
We follow all paternity-test guidelines for the language used in the report. For this reason, your paternity test results will say whether the possible fatherย IS EXCLUDEDย orย IS NOT EXCLUDEDย as the biological father of the child tested.
- IS EXCLUDED:ย Means that he cannot be the father because testing determined that he and the child do not share a biological parent/child relationship.
- IS NOT EXCLUDED:ย Means that he is likely to be the biological father because testing determined that he and the child do share a biological parent/child relationship with a high degree of probability.
IMPORTANT:ย Because we test up to 2,000 data-pointsโinstead of the standard 20 for a postnatal testโ the report provides a conclusion only and does not include all genetic data.
Does the report include information about the pregnancy other than paternity?
No; this test gives results for paternity only, with optional gender identification.
How much does a prenatal paternity test cost?
Call us directly for information about pricing and current specials.
Is a prenatal paternity test covered by health insurance or Medicaid?
Because this is not a clinical diagnostic test, paternity testing of any kind is not covered by health insurance or Medicaid.
Do you protect my privacy?
We take our customersโ privacy very seriously: both for your case and your DNA data.
- We will not release any information about your case to anyone without your authorization.
- We will always follow any special instructions you give us for communicating with you or other parties involved in your test.
- We never release test results over the phone.
Home Paternity
Can I do a home paternity test if I need results for child support or custody?
No; you should not do a home paternity test if you need results for child support, custody, or any other legal reason. Courts do not accept results unless they are from aย legal DNA test that maintained a strict chain-of-custody process. If you need results for court, contact one of our specialists for a no-obligation, free consultation.
How soon can you DNA test a baby after birth?
You can DNA test a baby after birth as soon as the baby has been cleaned up by hospital staff. Because a cheek swab is used, itโs important that the babyโs mouth be free from meconium, amniotic fluid, breast milk, or formula when doing the DNA collection.
What types of samples does DDC use for a home paternity test?
DNA is collected by test participants at home, using cheek swabs (also called buccal swabs). Cheek swabbing is a quick and painless way to collect cheek cells containing DNA. This isย notย a saliva test. To prevent swabs from getting โtoo wet,โ avoid gum areas and do not spit on the swabs. If they seem very wet, wave swabs in thefull instructions fo air for 60 seconds prior to placing them in the paper sample envelopes.
Is there a difference in accuracy between cheek swabs and blood?
Can a home paternity test be performed without the mother?
Yes; a home paternity test can be performed without the mother. If the mom cannot or does not want to be tested, we can still perform a home paternity test. A โmotherlessโ test could require more extensive analysis to produce conclusive results, but the results are just as accurate as those of a standard paternity test with the mother included. Keep in mind that consent from a legal parent or guardian must be obtained for testing a minor child. If the mother participates in a home paternity test, she is guaranteed to receive a copy of the test results.
Are home paternity tests accurate?
Home paternity test results are accurate for the samples provided to the laboratory. For at-home testing, the lab relies on test participants to make sure samples being analyzed by the lab belong to the correct people. If you do not trust other participantsโ integrity with submitting correct samples, you can either make sure youโre all together in the same room during swabbing or you should choose aย legal paternity testย (with witnessed DNA collection) instead.
The DDC Dual Processโข system adds an extra layer of surety to the accuracy of your test results. Each post-natal paternity test is performed twice by independent teams, so you can be confident in your results.
What happens if the tested parties live in different cities or states?
The easiest thing to do if tested parties live in different cities or states is to call us during business hoursย to set up the test, and weโll take care of sending DNA-collection kits to the different locations.
Can a paternity test be performed if the alleged father is missing or deceased?
A paternity test cannot be performed if the alleged father is missing or if he is deceased and no blood card is available from the funeral home. However, other testing options are available in these types of situations. DDC specializes in finding alternative family members to test to determine the true biological father.Other tests include:
There are two possible fathers and theyโre related. Is this a problem?
If two possible fathers are related as full brothers or father and son, they may share many of the DNA markers used in paternity testing. This means that if the laboratory is not aware of these relationships, both men could test positive as the childโs biological father. DNA testing is strong enough to determine paternity in a case involving closely-related fathers, but the laboratory must be made aware of these situations before the testing process begins.
DDC offers two options for cases involving possible fathers who are related:
Option 1:ย Test both fathers, the child, and the mother at the same time. By comparing both fathersโ DNA profiles with the childโs DNA profile, our expert laboratory staff can achieve accurate and conclusive test results. There is an added fee for the additional father.
Option 2:ย Test one father with extended analysis. This option is for when only one of the fathers is available for testing. To produce a conclusive result, we must perform extended testing and statistical analysis. There is an additional fee for the extended testing and analysis.
If your testing scenario involves two possible fathers who are closely related, contact us to set up your test
I live in New York State. Can I do a home paternity test?
Per the New York State Department of Health (NYSDOH), New York residents canย onlyย do a legal paternity test with a prescription from their doctor or attorney.ย See testing guidelines for New York State here.
How long does it take to get DNA paternity-test results for a home test?
How will I receive my results?
What do test results look like, and how do I interpret them?
We follow all paternity-test guidelines for the language used in the report. For this reason, your paternity test results will say whether the possible fatherย IS EXCLUDEDย orย IS NOT EXCLUDEDย as the biological father of the child tested.
- IS EXCLUDED:ย Means that he cannot be the father because testing determined that he and the child do not share a biological parent/child relationship.
- IS NOT EXCLUDED:ย Means that he is likely to be the biological father because testing determined that he and the child do share a biological parent/child relationship with a high degree of probability.
A paternity test result includes a table that lists:
- The allele sizes of the different DNA markers examined and used in the statistical analysis portion of the test (i.e., the DNA profile)
- A Probability of Paternity value
- A Combined Paternity Index (CPI) value
You will want to focus on the probability of paternity percentage. A result of 0% means the alleged father is not the biological father; a result of 99.99% or higher means the alleged father is most likely the biological father. The CPI value represents the odds against another random, unrelated, untested male in the population having the same results as the tested man.ย IMPORTANT:ย Paternity testing is calculated using statistics. Therefore, a probability of paternity can never be 100%, because that perfect score would require testing every man on earth with the same racial background of the man testedโwhich isnโt possible. A probability of 99%+ is considered conclusive for paternity.
Can I use my home paternity test results to obtain child support?
Do you protect my privacy?
We take our customersโ privacy very seriously: both for your case and your DNA data.
- We will not release any information about your case to anyone without your authorization.
- We will always follow any special instructions you give us for communicating with you or other parties involved in your test.
- We never release test results over the phone.
Legal Paternity
Will my test results be legally binding?
DDC strictly adheres to the chain-of-custody procedure as outlined by the AABB, and this makes our test results legally defensible. More judges in more courtrooms will see DDC reports than any other paternity report. Many of our patients use their test results for legal purposes such as child custody, child support, immigration, Social Security benefit claims, inheritance claims, and more.
You must call the lab directly to set up the test.

Can I use my legal paternity test results to obtain child support?
Testing through DDC follows a strict chain of custody, which makes our results defensible in courts and other government agencies. Many of our patients use their test results to obtain child support and for other important legal purposes, such as validating claims for Social Security benefits or inheritances.
What does โchain of custodyโ mean?
The chain of custody process is what makes a DDC legal paternity test results legally defensible in courts and other government agencies. It involves three main aspects:
- The tested parties are properly identified when their samples are collected. (Their government-issued IDs are verified and photocopied.)
- The DNA samples are collected by a neutral third partyโsomeone who has no personal interest in the outcome of the test (e.g., a hospital, clinic, or laboratory staff person. DDC will coordinate this collection).
- The samples are tamper-taped, securely packaged at the collection site, and carefully inspected upon receipt for any evidence of tampering.
When these requirements are satisfied and documented, the results are legally defensible. This means that the patients can use them for legal purposes such as child custody, child support, immigration, and more.
This test must be set up directly through DDC. Weโre ready to help.
How soon can you DNA test a baby after birth?
You can DNA test a baby after birth as soon as the baby has been cleaned up by hospital staff. Because a cheek swab is used, itโs important that the babyโs mouth be free from meconium, amniotic fluid, breast milk, or formula when doing the DNA collection.
How soon can I have my sample collected?
Because we have sample-collection sites all over the world, we are be able to schedule an appointment for you quicklyโoften on the same day that you call.
What do I need to bring to the appointment?
All adult test participants must bring a valid government-issued IDโsuch as a driverโs license, state ID, military ID, or passportโto the sample collection appointment. For minors, a recent photo is required, although the collector is likely going to take a photograph of all the tested parties, and this will suffice. In addition, the childโs legal custodian needs to sign a consent form allowing the minor to be tested.
What will happen at the sample collection appointment?
When you arrive at your appointment, you will need to present proper identification, which the sample collector will verify and photocopy.
After you are properly identified, you will need to sign a form giving your consent for the test. If you are the legal custodian of a tested minor, you will have to sign the form on behalf of the child.
The collector will collect your DNA samples using simple buccal swabsโcotton-like swabs that he or she will rub against the inside of your cheek to gather loose cheek cells. The collector will then send all the samples to our laboratory.
Our collection process is designed to be convenient, simple, and painless!
How long does it take to get DNA paternity-test results for a home test?
Results are posted 2 business daysย after samples are received at the lab. 1-day or same-day results once samples arrive at the lab are available for an additional fee.
