DNA Test - San Diego, California

San Diego CA DNA Testing Locations

Types of DNA Tests at our San Diego, 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 San Diego DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

San Diego, California - DNA Testing

Establishing paternity in San Diego, California

If you are unmarried and you and your partner have a child, ensure that your child has the same rights and access to benefits as a child born to married parents. There are three simple ways to establish paternity in San Diego, California.

If the child is born within the marriage, the husband is automatically considered as a legal and biological parent. If this is not the case, you can file a Voluntary Declaration of Parentage form. The third option is a determination of the Court.

Challenging paternity in San Diego, CA

When a man is told to be the father of a child, but he is not sure he truly is the biological father, he can request a DNA test to determine paternity.

Thanks to easy DNA tests usually done by cheek swab, parental relationships can be established. The mother, child, and a man considered to be the father must undertake the test to see whether the man is the biological father.

If you decide to undergo a genetic test, then be aware that the court will not accept private genetic testing as evidence in paternity cases unless the court ordered the test. If you don't want to go to the court, you can also visit the Department of Child Support Services, which performs the testing and is usually free of charge.

San Diego, California: Proving paternety

Parentage laws can be tricky and complicated, especially in situations when there was already a court order that established paternity, and after that, the mother wants to ask for DNA testing. There may be some complications in same-sex parenting situations. Also, there may be issues when the law already named someone the legal father even if the genetic test says that he is not.

If you need more information about challenging paternity in San Diego, California, you can visit the section on Disputing Parentage.
