Home Aunt Uncle Avuncular DNA Test With 46-Marker Analysis

A standard DNA test analyzing 20–22 markers is often sufficient for direct paternity (parent-child), where the child inherits exactly 50% of their DNA from the father. However, in an avuncular (aunt/uncle) test, participants only share roughly 25% of their DNA.

• Higher Statistical Power: Analyzing 46 markers provides more than double the genetic data of a standard 22-marker test. This significantly increases the "Power of Exclusion" and the "Likelihood Ratio," which are the statistical tools used to determine a match.
• Reduced Inconclusive Results: Because the shared DNA between an uncle/aunt and niece/nephew is much lower than in direct parentage, standard 20–22 marker tests have a higher risk of falling into the "inconclusive" range (typically 10%–89%). A 46-marker test is often the most powerful option available to avoid this.
• Comparing 46 marker tests Against 20-22: While 20-22 marker tests are generally accurate for direct father/mother -child relationships, 20-22 marker test are more often insufficient for more distant "relational" testing (like aunt - uncles, siblings, or grandparents). The 46-marker test is the "Premium Gold Standard" for relational cases and help to ensure the results are conclusive.

If you are not testing the mom, the 46-marker test is scientifically superior for obtaining a definitive answer when compared to a 20 or 22 marker test.

Avuncular DNA testing will determine the statistical probability of participants sharing a biological relationship as that of aunt-uncle and niece-nephew. Thus, an avuncular test can conclusively prove or disprove paternity.

It isn't uncommon for test participants to live too far apart to get together and do an avuncular DNA collection.  We offer an option to have multiple collection kits shipped out for these situations. When you place your order, simply choose the option for an additional address. We send each collection kit for all addresses on your order within the contiguous USA with the same shipping method as the first.  Before leaving the lab, the collection kits are linked through reference number and bar codes.  When the samples are received back in lab, they are matched to your case through the bar code and reference numbers.

A Y-STR test is a good option to consider for two males that would like to determine whether or not they are related on the paternal side. For example an uncle and nephew who want to determine if the alleged uncle’s brother is the father of the nephew. The Y-STR test looks at the Y-Chromosome that is passed from male to male in any unbroken male lineage. In this case, the alleged father and uncle will share the same Y-chromosome inherited from their common father. Likewise, the nephew will also have the same Y-STR passed down to him by his father. Y-STR is very unique, similar to a fingerprint and virtually unchanged for several generations. When Y-STRs are compared, the result is accurate and consequently produces a “Yes” or “No” answer to the question of whether or not the two tested males related through the male lineage.

The purpose of most avuncular testing is to indirectly determine paternity. In contrast, if a relationship is trying to be established on the mother’s side, an X-SV test offers a conclusive answer regardless of gender. Additionally, other relationship tests may also help establish paternity or maternity, such as a Siblingship test, or a Grandparentage test with one or both of the alleged parent’s parents. Alternately, consider a family reconstruction test if more than one paternal relative can participate in a DNA test.

The avuncular DNA test process is very simple. DNA is collected with a cheek swab, which is also called a buccal, swab. Rub the swab against the inside of the cheek to collect skin cells from the inner cheek and gums.  We conduct all of our tests twice.  For that reason, we supply  2 buccal swabs per person in your collection kit. Take a swab on each side of the mouth. It is best to rinse the mouth with water and refrain from smoking or drinking coffee or tea for 2-3 hours before the DNA collection. After collecting the DNA, place the samples in the prepaid return mailer.  Finally, simply drop the samples off at the courier’s location or drop box to send the lab.

When all avuncular samples are in the lab, you will be notified by email that testing has begun. The test results from your aunt-uncle DNA test will be e-mailed in 2-3 business days. If purchased, hard copy results are sent to the billing address unless otherwise noted.

We ship our collection kits with FAST & FREE USPS delivery Monday through Friday to physical addresses in the contiguous USA. Orders received and processed by 12:00 PM EST are shipped the same business day. Orders received after that time ship the following business day.

Our avuncular DNA test package comes complete with testing kit, DNA analysis and test results. Some companies advertise that you can make your collection kit by using your own Q-tips®. However, we do not recommend this. Although doing so may save the company money, it may cause costly problems for you. There is a risk of multiple DNA samples being found on Q-tips® that are not sterile, or that may be handled by more than one person. Q-tips® you may have in your home could already have DNA from other sources on them. For this reason, we send your aunt/uncle DNA collection kit containing sterile buccal swabs to you at no charge. We ship the collection kit to you via FREE USPS rushed delivery so you have your sterile medical swabs as ready for use fast.

Our informational test provides you with peace of mind as to whether or not an aunt/uncle relationship exists between test participants. For avuncular DNA test results that are admissible in a court of law or other agency, purchase our accredited legal aunt/uncle DNA test. Our legal avuncular DNA test results can be used as admissible court approved evidence in child support, visitation rights, change name on the birth certificate, estate, wills, probate situations, and more. If the embassy, USCIS or Dept. Of Homeland Security requires accredited DNA evidence of a biological aunt/uncle relationship for an immigration case, then contact us for information on how to get an immigration DNA test.

The most common method of DNA collection is through a cheek swab.  However, we understand there are times when a test participant is unable to submit a swab, such as may be the case where a family member may be deceased, incarcerated or otherwise unavailable. For these reasons, we offer forensic processing services for other types of DNA samples. Ear wax, hair (with the root ball attached), mucous on a tissue or handkerchief, finger or toe nail clippings, and toothbrushes are common forensic samples. Additionally, in certain cases blood or tissue samples may be available from a medical examiner or coroner’s office. Forensic sampling prices apply for non-standard samples. For pricing and more details on this process, please contact a DNA Case Manager.
