DNA Testing Guide

DNA testing has become one of the most powerful tools for reuniting families separated by adoption scandals. This comprehensive guide will help you understand how to use DNA testing to find biological relatives.

Why DNA Testing Matters

When official records have been falsified or destroyed, DNA provides scientific proof of biological relationships. Even when documentation is incomplete or misleading, your genetic code tells the truth about your family connections.

DNA testing can identify close relatives like parents and siblings, as well as more distant cousins who may have crucial information about your family history.

How to Get Started

Step 1: Order Your Test

We recommend testing with at least 2-3 different companies to maximize your chances of finding matches. Each company has different users in their database.

Step 2: Provide Your Sample

Most tests require a saliva sample. Follow the instructions carefully to ensure accurate results. Avoid eating or drinking for 30 minutes before providing your sample.

Step 3: Wait for Results

Results typically take 4-8 weeks. You'll receive an email when your results are ready. Be patient - this waiting period is normal.

Step 4: Review Your Matches

Start with your closest matches. Look for people who share significant amounts of DNA with you - these are likely to be close relatives.
