DNA Test – Fullerton, California

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.

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

Fullerton, CA – DNA Testing

Establishing Paternity in Fullerton, CA

Under California law, when a married couple decides to have a child, legal paternity is automatically established at the time of birth as it is assumed the husband is the biological father. On the other hand, if two Fullerton, CA residents have a child out of wedlock, legal steps will need to be taken in order to properly establish paternity over a child.

Following the child’s birth, both parents will be presented with the opportunity to sign a Voluntary Declaration of Paternity. This form should only be signed if there is full confidence in the man being the child’s biological father. If there is any doubt or either party does not agree to sign the form, it’s best for the wellbeing of a child that a paternity case is filed through an Orange County Family court or Child Support Services office.

Once a paternity case is filed, a judge will most likely order court-ordered DNA testing to confirm the child’s biological father and legally establish paternity. Steps may then be taken to request child support services and/or establish a co-parenting schedule for the child.

Dealing with Unique Paternity Cases in Fullerton, CA

In certain paternity cases, a Fullerton man may discover he is not a child’s biological father after having already signed a Voluntary Declaration of Paternity. In the state of California, if this discovery is made within 60 days of filing the declaration, he may submit a Declaration of Paternity Recession.

This legal filing will cancel the legal relationship previously established between him and the child. If the 60-day mark passes, he will then need to present his case in court. From here, an Orange County Family judge will likely order DNA testing to legally confirm the man is not biologically connected to the child to cancel the two’s legal relationship.

Experts in Fullerton, CA Say…

If a Fullerton, CA mother refuses to allow a biological father to sign a Voluntary Acknowledgment of Paternity, he has the right to present his case in court and request DNA testing. According to Fullerton Family Attorney Evelina Miller, once the father has been determined to be the biological father of a child, he obtains certain rights regarding the child. These include the request for custodial rights, legal visitation, and decisions for the child, such as schools and healthcare.
