About Us

Gotta Know DNA Services provides legal and personal DNA services, including paternity, prenatal paternity, and other testing services. DNA testing is available to clients in Houston, Texas, and the surrounding areas.

Our series of tests include paternity, prenatal paternity, ancestry by DNA, grandparentage (one or both paternal grandparents and child required), siblingship (test for full or half sibling relationship), maternity, avuncular (child and alleged uncle), secret paternity (alleged father or child), semen detection, and postmortem/estate planning (testing or storing samples from descendants and collected at the morgue).

In business since 2007, we pride ourselves on offering fast and affordable DNA testing. We are referred by more than any other lab in Harris County, and we accept and welcome referrals from surrounding counties. In fact, we are the preferred choice by courts and attorneys for AABB paternity and DNA testing in Texas. Additionally, we are headed by a nurse with more than 20 years of experience and a specialty in forensics. Our mission is to bring families together through DNA testing.
