Immigration Petitions

Frequently Asked Questions
What is an avuncular DNA test?
An avuncular DNA test determines the biological relationship between a child and the alleged father's brother or sister (the child's aunt or uncle). It is used to indirectly establish paternity when the alleged father cannot be tested. The laboratory analyzes 20+ STR genetic markers to estimate how likely the relationship is.
When should I use an avuncular test instead of a paternity test?
Use an avuncular test when the alleged father is unavailable for direct testing because he is deceased, absent, or unwilling to participate. If he has a full biological brother or sister who is willing to be tested, that aunt or uncle can be tested in his place. A direct paternity test is always more conclusive when the alleged father is available.
Should the child's mother also be tested?
Yes, including a sample from the child's known biological parent is strongly recommended. It lets the laboratory separate that parent's genetic contribution and focus on the markers tied to the alleged father's family line. This meaningfully strengthens the result.
How is the sample collected and is it painful?
Collection uses a painless buccal (cheek) swab that is gently rubbed inside the cheek for a few seconds. It is non-invasive and safe for participants of any age, including infants. You can use an at-home kit or test at a certified collection site.
Can avuncular test results be used in court or for benefits?
Only if you order a legal avuncular test, which is collected at a certified site with photo ID verification and documented chain of custody. Legal results may be used for court, Social Security benefit claims, and immigration petitions. A personal or at-home test is for private knowledge only.
How long do avuncular test results take?
Results are typically ready within 3 to 5 business days after all participant samples arrive at the AABB-accredited laboratory. If participants test at different locations, the timeline starts when the last sample is received. Call (866) 702-7644 for a free consultation and exact pricing.
