Legal Paternity DNA Testing — Accurate, Admissible, Affordable

A child inherits half of their DNA from the biological mother and the other half from the biological father. Paternity DNA testing compares a child's DNA pattern with that of an alleged father. When the alleged father is not biologically related to the child, the probability of paternity is 0%. When the alleged father is the biological father, we achieve a probability of paternity greater than 99.9%.

We offer legal paternity DNA testing that is fully admissible in court and legally defensible. Our AABB partner laboratory uses the most advanced and accurate technology to determine parentage with strict quality controls and chain-of-custody protocols.

DNA sample collection is simple and painless — a Q-tip-like cotton swab is used to collect a sample from inside the cheek. The sample is then courier-expressed to the laboratory for next-day delivery and analysis. Results are typically available within 2 to 2 to 5 business days.

Personal (non-legal) paternity testing is also available for those who simply want peace of mind. Our prepaid home DNA testing kits allow you to collect samples in the comfort of your home. Please note that personal test results are not court-admissible — if you think you may need legal results in the future, we recommend choosing legal testing from the start to save time and money.

We serve clients throughout California — including Oakland, San Francisco, Los Angeles, Sacramento, San Diego, Fresno, Riverside, and more — as well as all 50 states nationwide. If parties are located in different cities or states, we can coordinate testing at a partner laboratory site near each participant.
