Specimens we can test for DNA
The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the alleged father and child or children. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory.
Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone’s DNA, can also be tested. An Alternative Specimen DNA Test is done by ordering one of our testing kits online and shipping the specimens back to us.
Legal DNA Tests vs. “Peace of Mind” At-Home Tests
A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.
When deciding which type of DNA test is right for you, consider first what you might do with the results. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Lafayette DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Establishing Paternity in Lafayette, LA
Unlike a married Lafayette couple that is provided automatic paternity at the time of a child’s birth, when two unmarried parents have a child, both must legally establish paternity themselves. After a child is born, the first opportunity to legally establish paternity is presented at the hospital though an Acknowledgement of Paternity Affidavit form. This form must be completed within 300 days of birth to effectively establish paternity.
In some cases, a mother or father may not agree to the presumed paternity of a child and refuse to sign this acknowledgment. If either parent has a question over who the child’s biological father is, it’s highly recommended they file a paternity action through Lafayette Parish Family Court. From here, court-ordered DNA testing will be issued to effectively determine paternity. If results confirm that the presumed father is the child’s biological father and paternity is established, a mother can request further child support services from the father.
Dealing With Uncommon Paternity Issues in Lafayette, LA
While it is an uncommon situation, a married Lafayette woman may have a child by a man who is not her husband. Similar to common establishments of paternity, the state of Louisiana also offers Acknowledgement of Paternity Affidavits for children that are born under these circumstances. Titled Acknowledgment of Paternity Affidavit: Child Born of Marriage, the form requires the signature of the mother, husband/ex-husband, and biological father to properly establish legal paternity over the child.
Bear in mind, in order for Lafayette Family Court to accept this form, the affidavit must be accompanied by proof of DNA-based paternity testing with at least a 99.9% connection to the biological father.
