DNA Test - San Ramon, California

San Ramon CA DNA Testing Locations

Types of DNA Tests at our San Ramon, 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 San Ramon DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

San Ramon, California - DNA Testing

Establishing paternity in San Ramon, CA

In San Ramon, California, unmarried parents have two options to establish legal paternity for their child: sign the Voluntary Declaration of Parentage (VDP) or obtain a court order. If both parents agree about the biological father, they can sign the VDP at the hospital after the child's birth, with assistance from the hospital staff. Alternatively, they can sign the VDP at a later time.

If there are disagreements, lack of cooperation, or uncertainties about paternity, the mother and alleged father may choose to go to court instead. The judge may order a DNA test to confirm paternity in these cases. This method is painless and reliable, usually conducted with a simple cheek swab. The DNA specimens are sent to a lab for analysis, and the results are provided to the judge. From there, the judge can also determine custody, visitation, and child support if necessary.

San Ramon, California: Disputing paternity

Parents who wish to establish legal paternity should seriously consider the legal implications before signing a Voluntary Declaration of Parentage. Disputing parentage can be difficult, particularly when a court order has already established paternity. The laws on parentage in San Ramon County can be complex. Parents who wish to dispute paternity after it has been legally established often seek legal advice from a family lawyer.

Benefits of legal paternity in San Ramon, CA

Establishing paternity in San Ramon can come with benefits for both parents and the child, some of which can include:

The ability for both parents to participate equally in the child's life and make important decisions regarding education, religious upbringing, or health
Financial support from both parents for the child
Building an emotional bond between the child and both parents
Access to the medical history of both parents for the child
Access to health and life insurance, Social Security benefits, inheritance rights, and veterans benefits for the child, if applicable
Clear determination of custody, visitation hours, and child support through court
A sense of security for the child knowing their legal parents

Health Street offers legal DNA tests that provide accurate results and are admissible in a court of law. Unlike home DNA testing options, our legal DNA tests can establish a legally binding relationship for fathers, mothers, aunts, uncles, siblings, children, grandparents, deceased loved ones, the unborn, and twins.
