DNA Test - Lafayette, Louisiana

Lafayette LA DNA Testing Locations

Types of DNA Tests at our Lafayette, Louisiana clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

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.

Lafayette, Louisiana - DNA Testing

Establishing paternity in Lafayette, Louisiana

Parents in Louisiana must establish paternity if a child is born outside of marriage. The quickest way to do so is to sign an Acknowledgement of Paternity Affidavit, which will add the birth father to the child's birth certificate. Both parents must sign this affidavit, and two witnesses of a licensed notary must be present to make it valid.

The document can be signed in the hospital when the baby is born and must be submitted to the Vital Records Registry, but in most Louisiana hospitals, the staff can do that for you.

Another option for establishing paternity in Louisiana is a court order. Parents usually decide to go through court when the father refuses to sign an affidavit or when they are unsure about the biological father. The judge usually orders DNA testing, and if there is a 99.9 percent or higher match, paternity can be established.

Lafayette, LA: Benefits of establishing paternity

Establishing paternity has many legal and emotional benefits for both children and parents. There are numerous reasons why parents should establish paternity if they are not married:

Knowing both parents can help the child understand better their identity
The child will be able to build a relationship with both parents better
The child will have access to the medical history of both parents, which can help with uncovering possible genetic diseases
The child can get financial support from both parents
The child may gain access to other financial benefits such as Social Security, health insurance, pensions, veteran's benefits, or inheritance rights

The right to adoption is a critical right that parents can gain after establishing paternity. If the mother wants to give up the child for adoption, for example, the father must be notified. Once paternity is determined, the judge can also establish custody and visitation of the child and child support.
