Fullerton CA DNA Testing Locations

Types of DNA Tests at our Fullerton, California locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

Our Fullerton DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Fullerton, California - DNA Testing

How to Establish Paternity in Fullerton, CA

Unmarried Fullerton parents who are expecting or have recently had a child must establish paternity for the biological father to gain paternal rights and responsibilities over his child. Fortunately, Fullerton parents have an easy and cost-free method to establish paternity in the state of California through the California Parentage Opportunity Program.

The California Parentage Opportunity Program enables two Fullerton parents to establish paternity by completing a Voluntary Declaration of Parentage Form at the hospital or through an Orange County Child Support Services location. This completely voluntary process must be completed by both parents and should only be done if there has already been DNA paternity testing or if there is full confidence in the child's biological father.

In instances where either Fullerton parent refuses to complete the steps necessary to establish paternity, the other will need to file a petition through an Orange County Family Court. A legal petition allows an Orange County judge to mandate that DNA testing is completed to properly identify the biological father and establish legal paternity.

Highlighting the Importance of Establishing Paternity in Fullerton, CA

When it comes to protecting the wellbeing of a child, Fullerton parents must legally establish paternity. In addition to providing a Fullerton father with both his paternal rights and his legal name on the child's birth certificate, establishing paternity presents a haul of child benefits, including health insurance, inheritance, and social security benefits. Similarly, the state of California will require paternity to be legally established for a primary guardian to receive child support services.

Disestablishing Paternity in Fullerton, CA

In certain unforeseen situations, a Fullerton father may later learn that he is not the biological father of the child whom he claimed. In the state of California, if a Fullerton father makes the discovery that he is not a biological father within 60 days of establishing paternity, he may submit a Declaration of Paternity Recession to disestablish paternity and any child support agreements. If the 60 days have passed, the establishment must be challenged in court and will typically require professional legal assistance and proof of DNA testing.
