DNA Test - Sunnyvale, California

Sunnyvale CA DNA Testing Locations

Types of DNA Tests at our Sunnyvale, California clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

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 alleged father and child or children. 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 ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. 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. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Sunnyvale DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Sunnyvale, California - DNA Testing

Search for Speech Material Reunites Sunnyvale Mayor with Birth Family

After taking a DNA test nearly a decade ago, Sunnyvale Mayor Larry Klein hadn't thought much more of it. However, when he logged back into his account while doing research for a speech, he was shocked to come across a message from a potential relative who was looking to connect.

Klein, who had been adopted and never met his birth family, reached out to the woman who turned out to be his half-sister. He then learned that he had another sister whom he shared with his birth mother. The three met in person, and during their conversation, Klein learned that his birth mother was alive and well and living nearby in Southern California. He was eventually able to meet her in person as well and says he is thankful for DNA testing's ability to reunite families.

The Importance of Establishing Paternity in California

In the state of California, when a child is born to unwed parents, he or she does not have a legal father until steps are taken to establish paternity. According to attorneys at The Law Offices of Sandra J. McManus, which serves clients in Sunnyvale and the surrounding area, there are many benefits of establishing legal paternity.

Without legal paternity, a child won't have access to his or her father's Social Security benefits. In addition, the courts cannot rule on important issues like custody, child support, and visitation until legal paternity has been established.

How to Establish Paternity in Sunnyvale CA

When a child's parents are not married at the time of birth, paternity (also called "parentage") is established in one of two ways:

Getting a court order

A voluntary declaration of parentage is a legal document that can be signed at the hospital when the child is born or at a later date. When processed, this form has the same effect as a court order, without the need to go to court.

If there is a dispute about the child's paternity or one parent will not voluntarily sign the declaration, an interested party can start a parentage case by filing paperwork at their local courthouse. The Sunnyvale courthouse is located at 605 W. El Camino Real, Sunnyvale CA.
