    People Love Us.

    "My baby’s dad passed away before he could sign the “Acknowledgment of Paternity.” Once she was born, we tested her against her dad’s parents’ DNA and confirmed their filiation. I know it will give her peace of mind when she’s old enough to understand." - Jane

    "My wife and I had issues when we got pregnant and I wasn’t never sure I was the dad. CRI Paternity ended my constant questioning assuring me my son and I are related." - Mark

    "My daughter and I never looked alike so, when her mom and I separated, I decided to take a CRI Paternity test. I would never renounce to my parental rights so I chose the non-legal test. Unfortunately, I ended up not being her biological father. It doesn’t change the way I love her, but it did make me feel better about leaving her mother." - Dwayne

    "I was adopted and never knew my biological parents. Being a mother myself, I needed to know where I was coming from. I took CRI Genetics Ancestry Test first and learned a lot about my biological family. But I wanted more. I found my biological parents last year. It took me several months to contact them. They were teens when I was conceived and I understand why they put me up for adoption. We all took the CRI Paternity test together, just to be sure we were related. They are my biological parents, our DNAs proved it. I’ll never call them Mom and Dad, but I’m glad we are in each other’s life now." - Marie

    "My ex-girlfriend and I weren’t exclusive. After we broke up, she told me she was pregnant with my baby. I didn’t want to believe her without proof. Once the baby was born, we got tested with a CRI Paternity legal test. I am not the father and I am extremely happy about it. I wasn’t ready to be a father. And if my ex goes after my money, I’ll be able to fight it in Court." - Justin

    "My dad cheated on my mom a lot, she always stayed. Both of them passed when I was 19 and I had no other family. I found out recently that my dad had a kid when I was still a child. We met and got tested. We are half-siblings. Even if it hurts to think how my dad treated my mom, I have family and that’s all I ever wanted." - Aurora

    "When I decided to divorce my wife, she was angry and revengeful. She said I’d never see my son again, that I wasn’t even his dad. The thought hurt so much I decided to get tested. I am his dad, she can’t deny it anymore. And I can officially prove it thanks to the CRI paternity legal test I took. I’m fighting for custody and confident in my chances. Thanks to CRI Paternity, I am at peace." - Colin

    "I had difficulties bonding with my twins at first. Their mother and I were fighting a lot. I still believe she cheated sometime around the pregnancy, even if she’s always denied it. Twins don’t run in any of our families and I was only one step away from thinking my kids were not actually mine. My brother pushed me to get tested, saying that whatever the results were, knowing with certainty would help me. And he was right. CRI Paternity confirmed that I was my twins’ dad and our relationship changed since then. Being certain I am their dad made me a better father." - Vincent

    "My wife and I are African-American but our daughter looked mixed-race from the day she was born. She even has blue eyes when none of us does. I didn’t want to doubt my wife’s fidelity but I didn’t understand how it was possible. She offered to take a family DNA test, so I would be more at ease. Within a few weeks, CRI Paternity confirmed I was my daughter’s biological father. But I was still confused on how she could look so different than us. We went back on the website and saw we could upgrade for Ancestry reports, without taking the test a second time. We did it and now, it make sense. Both my wife and I have some European ancestors. She is 9.2% Irish, I am 11.9% German. Our daughter received both heritage." - Cameron

    F A Q

    CRI Paternity is a branch of CRI Genetics. CRI Genetics is an advanced team of scientists who work together based on the latest research in genetics, anthropology, and the social sciences to give you results. When you choose CRI Paternity DNA tests, you choose expertise and accuracy. Our results come with the guarantee of quality and peace of mind.

    We hold a Clinical Laboratory Improvement Act (CLIA) certification that regulates our laboratory testing and allows us to accept human samples for diagnostic testing. In the laboratory, CLIA quality assurance involves the entire testing process: pre-analytical, analytical (testing), and post-analytical processes.

    Some DNA testing laboratories examine 16 to 20 genetic markers “at no additional cost”, like they proudly say. Then they give you your results back within a day… Our internationally acclaimed DNA specialists will review and compare all the 527,414 genetic markers essential to give you a definite answer. We guarantee that you will receive your results within 8 weeks, or you’ll get your money back.

    Though verifying the relationship between an alleged father and child is most common, CRI Paternity can verify the relationship between ANY alleged relatives (mother, siblings, grand-parents, etc). The more family members tested, the more accurate your results. CRI Paternity DNA tests can be used regardless of the sex or the alleged relationship.

    A sample from the mother is not required, but it can be useful.

    CRI Paternity collects the samples via cheek swabs.

    You will receive 2 buccal swabs per person tested. Gently rub 1 swab on the inside of your cheek to gather cells (15-20 seconds). Detach its tip into the matching vial before repeating the operation with your other cheek. Then enclose both vials in the matching sample collection bag (make sure all the barcodes match).

    Buccal swabs and blood samples provide results with the same degree of accuracy. We chose buccal swabs for our Paternity DNA tests because they are the easiest and less invasive way to collect your DNA.

    An email will let you know that your Paternity results are ready within 3-8 weeks. Your results will be emailed to you directly.

    DNA paternity testing is considered a non-medical test. Thus it is not covered by health insurance plans.
