Legal Trio Test: It is used to determine paternity with greater accuracy by including the mother’s DNA in the analysis. This genetic test that involves three people: ➡️ the child, ➡️ the alleged father, and ➡️ the mother. How a TRIO DNA Test Works: DNA Sample Collection: All three individuals (child, alleged father, and mother) provide samples—typically via painless cheek swabs. DNA Analysis: The child’s DNA is compared to both the mother’s and the alleged father’s. Since the child inherits half of their DNA from each parent, the lab first confirms which genes came from the mother. The remaining genes must then match the alleged father for him to be confirmed as the biological father. Results: If the alleged father shares the expected genetic markers, the result is typically 99.99% or higher—meaning he is the father. If he does not match the required markers, the result will be 0%—he is not the father. Why Include the Mother? Including the mother: Helps eliminate any doubt about which DNA markers the child inherited from her. Makes the analysis clearer and more definitive, especially in cases with: Close relatives involved Unusual genetic mutations Court-admissible/legal testing When Is a TRIO DNA Test Used?
