DNA Test - Santa Clara, California

Santa Clara CA DNA Testing Locations

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

Santa Clara, California - DNA Testing

Local DNA Stories

In 2021, two long-lost sisters, both living in Santa Clara County, found each other, thanks to DNA testing. Kathleen Robinson found out she was adopted at age 9 and since then, hated celebrating birthdays. She said birthdays were hard, and she always wondered if her biological parents thought of her. But after years of searching for her biological family, she gained her long-lost family after using a DNA test. Deana Harn, her biological sister from Santa Clara County, became one of her best friends. The two Santa Clara County sisters spent their lives only living fifteen minutes apart from each other, with one in Milpitas and the other in San Jose.

Experts Say...

"If you know who your child's father is, but you have not put it writing and obtained an official judgment of paternity, the child will not be entitled to the father's Social Security benefits and will not have inheritance rights in the father's estate," said Santa Clara paternity attorney Sandra J. McManus, "Even if the father's name is on the child's birth certificate, it is very important to get an official judgment of paternity so that the child can get the necessary benefits if something happens to his or her father." McManus also said that establishing paternity is required to obtain child support, custody, and visitation court orders.

Proving Paternity for Child Custody Purposes in Santa Clara, CA

In Santa Clara, unmarried parents can establish paternity by signing a Voluntary Declaration of Parentage form as long as the man is the only possible biological father. When two parents sign the form, their signatures must be witnessed by an authorized witnessing agency. This can be done at the hospital at the time of the child's birth, at the local Child Support Agency Office, at the Office of Vital Records, through the court, or at the Santa Clara Welfare Department.
