    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.
