DNA Test - Castro Valley, California

Castro Valley CA DNA Testing Locations

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

Castro Valley, California - DNA Testing

Establishing paternity in Castro Valley, CA

When it comes to establishing paternity in Castro Valley, California, unmarried parents have two primary options. The first option is to sign the Voluntary Declaration of Parentage shortly after the child is born at the hospital. The hospital staff can provide assistance in navigating this process. By signing this legally binding document, the alleged father becomes the child's legal father. His name can be included on the birth certificate, and he can exercise his rights to custody or visitation hours.

The second option for establishing paternity is to go to court. Many parents choose this route when they face conflicts or have doubts about paternity. In court proceedings, the judge often orders a DNA test to be conducted, which is a quick and reliable method of determining biological parentage. The DNA test, typically performed through a non-invasive cheek swab, provides evidence to establish or refute paternity.

For individuals in Castro Valley, California, seeking to establish paternity or confirm a biological relationship, Health Street offers DNA and paternity testing services. Our tests are non-invasive and reliable, ensuring accurate results within a reasonable timeframe.
