Antioch CA DNA Testing Locations

Types of DNA Tests at our Antioch, 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.

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

Antioch, California - DNA Testing

Establishing paternity in Antioch, California

If parents are not married when a child is born, California law usually assumes the child has no legal father. Therefore, it is necessary to establish paternity. In Antioch, California, parents can establish paternity by signing the Voluntary Declaration of Parentage (VDP) or going to court. When parents agree about the identity of the biological father, they often sign a VDP after the baby is born at the hospital. The hospital staff can help them with the process.

Sometimes, parents disagree about paternity, do not communicate with each other, or are unsure about who the biological father is. Antioch parents often go to court to establish paternity in these situations. When they go to court, the judge will likely ask the alleged father and the child to undergo a DNA test. If DNA testing proves a father-child relationship between them, the judge can consider this evidence while establishing paternity. However, it is important to note that each paternity case is unique, and the judge may not always decide that the biological father should be the legal father.

After paternity is established, parents may also have the court establish visitation hours, custody, or child support.

Antioch, California: Disputing parentage

When a man is told he is the biological father of a child, but he disagrees, he can dispute parentage and opt for DNA testing. DNA is inherited from both parents, so if he and the child take a DNA test, it can easily prove whether he is the biological father. However, if the paternity has already been established, for example, by signing the Voluntary Declaration of Parentage or the court order, challenging it may be much more complex. Since each case is different, many parents choose to contact a family law facilitator in this situation.

Also note that if a DNA test is taken at home, it may not be accepted by the court, and a legal DNA test will usually need to be ordered instead.
