What is an avuncular DNA test? Avuncular testing is indirect paternity testing.

An Avuncular DNA test, also known as an Aunt/Uncle DNA test,  allows the full brother or sister of the suspected parent to participate in a DNA test to verify their biological relationships with a possible niece or nephew.  The uncle – aunt DNA test determines the statistical probability of those who submit their DNA for testing showing if a biological relationship of aunt or uncle and niece and/or nephew is likely to exist.

There  are many reasons why a biological parent may not be available for testing, and this DNA test an accurate way to learn the truth about the relationship without taking a paternity or maternity DNA test.

Avuncular DNA testing can provide a conclusive result to in-directly establish paternityor maternity when the suspected father or mother is not available for a direct paternity or maternity test.

An avuncular test should only be done with the alleged parent’s full sibling. The test can be done with either a brother or sister of the alleged parent, who share the same mother and father. Performing an avuncular DNA test with the alleged father’s half sibling, increase risks of weak or wrong leaning conclusions, and for that reason we do not offer Avuncular testing using a half sibling of the parent.

How accurate is Avuncular DNA testing?

The more genetic markers that are examined means a more accurate DNA test result. It's a scientific fact. That's why we guarantee to provide the most accurate Avuncular DNA test available

Aunt-Uncle DNA testing is based on the statistical probability that two or more people are related by bloodlines. The industry standard for DNA testing of this type compares only 16 alleles (genetic markers) in an attempt to arrive at a conclusion regarding the suspected relationship.

Journey Genetic Testing holds the position that utilizing the industry standard 16 markers is not a sufficient standard to perform adequate testing for an Aunt/Uncle relationship due to not enough markers being tested to feel confident about the results.

When only 16 markers are being considered in the testing process, there is a very good possibility that an inconclusive result will be reported. Even worse, a false negative or false positive is also a potential outcome.

The more genetic markers that are examined means a more accurate DNA test result. It's a scientific fact. That's why we guarantee to provide the most accurate Avuncular DNA test available

Journey Genetic Testing will only perform Avuncular DNA tests with a base of 24 genetic markers as part of our policy and procedural standards. If a conclusive result is not reached with 24 markers, the test will automatically be upgraded to test additional markers up to a total of 35. The DNA test result we provide you will show the strongest result possible for the relationship. We guarantee the DNA testing results we deliver to be at least 1,000 times more powerful than the standard 16 marker processing occurring today.

While we can certainly obtain an accurate result with just one aunt/uncle and one niece/nephew being tested, we do suggest that if possible you add the mother's DNA sample. Journey Genetic Testing does not charge an additional fee to test the mother's DNA sample if it is submitted at the same time as the other DNA samples. If the mother is not available to provide a DNA sample we will still perform the testing, providing a result based on the genetic profiles of the suspected aunt or uncle and niece or nephew.

Avuncular DNA Test FAQs

During the test, DNA samples are collected through a swab of the cheek. These samples are then analyzed to see if they share genetic similarities that would define a relationship of aunt or uncle and niece or nephew. A child inherits half their genes from their biological father, while the father shares about half of his genes with a full sibling. So, around half of the child's paternal genes will match those of the father's full sibling. Only a full sibling of the father can give an accurate avuncular test.


The primary reason someone would choose an avuncular DNA test is to determine paternity when the presumed biological father is absent, usually because he has passed away, is incarcerated, or is not willing to submit to standard DNA testing. Determining paternity can be a critical help in many situations, including custody and child support orders, inheritance claims, acquisition of Social Security survivorship benefits, and establishing a family relationship for immigration sponsorship.

If possible, the mother's DNA sample is recommended as part of the child's test. This streamlines the entire process, as it helps the lab identify and eliminate the mother's DNA from the child's genetic makeup. There is no additional cost for the mother's DNA sample if it is included with the initial testing.

Results are reached based on two factors: the number of genetic matches between the child and the presumed aunt or uncle and the statistical likelihood that those matches would occur randomly. These two numbers are calculated and compared to reach a percentage of probability. The higher the percentage of probability, the likelier it is that there is an aunt/uncle relationship. Bear in mind, however, that an avuncular test doesn't have to show 100 percent probability to be deemed scientifically accurate; if the percentage shown on the report is 90.0% or higher, it is generally accepted that the results are conclusive.

Yes! If the participants live at different addresses, different cities, or even in different states, we can send separate kits to everyone involved.

In order to send a second kit to another address simply select the option for additional kits on your order form. and enter the secondary address in the section asking where the kits are being sent to.

  • Home DNA tests are done to the same standards as our AABB legal paternity tests. Our tests are performed in a fully CAP, AABB accredited and ISO 17025/9001 certified laboratory. All of our paternity and family DNA testing services follow strict and validated procedures for processing samples to guarantee the highest degree of accuracy. Our testing process looks for 24 genetic markers ensuring you receive 100% accurate test results.

Avuncular DNA Sample Collection

The most accurate method of obtaining DNA for an avuncular DNA test is to use a buccal (mouth) swab, which is very similar to a "Q-tip" cotton swab. The swabs are rubbed on the inner cheeks of the mouth of those being tested.  The process is simple and fast. We provide all the materials needed for the DNA collection in our Journey Genetic Testing Test Kit.

However, we know that sometimes it is not possible to obtain a buccal swab sample. We are often able to test discreet alternative DNA samples. To learn more about non-standard, alternative DNA samples that we can test, CLICK HERE.

Your DNA collection kit will have detailed step-by-step instructions on how to collect your swab sample. You can also read more about how to take a home DNA test by going to How To Collect A DNA Sample At Home.

If you need to send one or more of the DNA collection kits to a different address, we can do that as well. Just indicate how may collection kits you need when you complete the order form, and enter the addresses for each kit in the area of the form where it asks where the kits are being sent.

Avuncular DNA Test - Making Your Own DNA Kit (MYOK)

All avuncular DNA test orders include a DNA collection kit sent to the designated address on the order form. We understand that you may be in a situation where you do not want anything being mailed to you, to allow additional privacy.

Journey Genetic Testing allows you the option to make your own testing kit when collecting and returning DNA samples to us. This option can save money on shipping a DNA kit to you,  as well as save you time as you can ship directly to us  without waiting for the testing kit to arrive.

To choose this option please select the "Make My Own Kit" option on the order form for the particular test you are seeking. You will find the order form on the information page for that particular test. For example, paternity test order forms are found on the paternity page, sibling order forms are found on the sibling page, and so on.

Upon finalization of your order (during regular business hours) you will be e-mailed a submission letter with your unique Journey Genetic Testing case number and the address for mailing your samples. The processing of the samples is conducted in the same time frame as if you used one of our kits - in as little as 1 business days for paternity, maternity, sibling, grandparent, avuncular, and twin zygosity tests!

Non-standard samples being submitted must fit into a standard envelope. If necessary please trim the item to fit (for example a hat band, a piece of clothing with blood, etc) into a regular envelope while making certain the specific area to be tested is included.


It is strongly suggested that if you reside outside of the United States and wish to order DNA testing that you use this option as the most cost effective and time efficient method to get the answers you need and deserve.

Please note that we are unable to process any DNA samples without a Journey Genetic Testing case number. Samples that arrive without a case number will be discarded.

Avuncular DNA Test Results - Example of Test Report

In Avuncular DNA testing the results are based on a probability, or likelihood, that two or more individuals are related with the biological father of the nephew or niece being tested. According to AABB standards, a conclusive range is a 91% or greater (all the way to 99.99%) probability of the tested relationship.

We have provided two examples of how Avuncular DNA results may appear. Our Aunt or Uncle DNA Testing kit can determine with 100% accuracy, up to a 99.99% positive proof of relationship or 100% exclusion.

Avuncular DNA Test Result Exclusion

This result shows that the relationship is not supported by the genetic evidence from the DNA samples that were submitted. This means that the Aunt/Uncle and/or Niece/Nephew is not probable. We refer to this as an "exclusion of the relationship."

Avuncular DNA Test Result Confirmed

This result shows that the relationship is supported by the genetic evidence from the DNA samples that were submitted. This means that the Aunt/Uncle and/or Niece/Nephew is confirmed. We refer to this as an "inclusion of the relationship."

The conclusive range for these results are 91% inclusion. We do not guarantee that results will fall into this conclusive range, however with our advanced DNA testing of up to 35 DNA markers (when needed), Journey Genetic Testing provides conclusive results for Aunt/Uncle tests in up to 97% of cases (99% if the mother of the child is included).

I thought I could do other tests with this kit, but this test is only for an aunt/uncle and their maybe niece/nephew. I liked the fact that the price I paid included everything: the test, the lab fees, and a prepaid shipping envelope to send my DNA to the lab. The test was very accurate in my case. The lab emails the results so I got them as soon as they were finished. The lab was fast at getting me my results back as well!

Although I did not like the results I received I understand that is out of the companies control. I received my test two days after I ordered it. I live in Oklahoma and I sent it to the on Monday received an email on Tuesday that they got it (they gave me a prepaid overnight label included with my test) and had my results by Thursday afternoon. It was very quick and efficient. I love that no one has to know that I did this and I now have peace of mind without affecting anyone’s lives. I would definitely recommend using Journey Genetic Testing.
