Sibling DNA Test — Informational
Find out if you share one or both biological parents — private results for personal peace of mind
When the alleged father is unavailable, deceased, or unwilling to test, a sibling DNA test can still provide answers. The informational sibling test compares the DNA of two individuals to determine whether they are full siblings (same mother and father), half siblings (one shared parent), or unrelated. Results are private and delivered to you only — not formatted for court use. If you need legally admissible results, see our Legal Sibling DNA Test.
