DNA Test - Chico, California

Chico CA DNA Testing Locations

Types of DNA Tests at our Chico, 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

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Chico DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Establishing paternity in Chico, CA

If parents are married when the baby is born, the husband is automatically considered the child's legal father in Chico, California. However, unmarried parents must establish paternity. Parents can either sign a Voluntary Declaration of Parentage (VDP) or go to court.

If parents have no doubts about paternity, they can sign the VDP at the hospital once the child is born. However, sometimes, parents disagree about paternity. In that case, parents often choose to go to court. The judge will usually order the alleged father and the child to take a DNA test. Genetic testing is a painless and quick method of establishing father-child relationships and proving whether they are related. If the test returns positive, the judge may decide to establish paternity. It is important to note that other factors and convincing evidence may also influence the judge's decision.

Chico man took DNA test and helped reunite mother with her long-lost brother

In December 2019, Joshua received news that would change his mother's life forever. He wanted to learn more about his family history, but he never imagined he would help to reunite his mother, Ramona, with her long-lost brother. Joshua took a DNA test, and soon after, he got a message saying he was related to Tim. At first, he started to dig more into it, and shortly he realized he had found his uncle!

Joshua's mother had three siblings who were put up for adoption, and she had been looking for them her whole life with no luck. She tried everything, but nothing worked until Joshua took the DNA test. When Joshua found out about this exciting news, he called his mother. She was shocked but excited.

Tim and Ramona called each other and spoke for hours. Her brother shared that he had also been looking for his family. Now, they are finally reunited, and they could not be happier! Joshua hoped to also visit his uncle soon, but it was a bit complicated due to all the pandemic restrictions.
