DNA Test – San Leandro, California

San Leandro CA DNA Testing Locations

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

Benefits of Establishing Paternity

According to Alameda County paternity lawyer Gerard A. Falzone, there are many important reasons to establish paternity. Until legal paternity is established, courts are unable to rule on critical factors including child support, custody, and visitation. When a child knows who their father is, they can access important medical information that may be necessary to prepare for genetic and other health issues. A child’s legal father can have a say in how the child is raised, including where they go to school and religious issues.

How to Establish Paternity in Alameda County

In Alameda County, if parents are married when a child is born, paternity is automatically presumed and no further action is needed. However, if the parents are unmarried, they must take steps to establish legal paternity.

There are three ways for unmarried parents to establish paternity. California’s Paternity Opportunity Program (POP) allows unmarried parents to voluntarily acknowledge paternity without the need for genetic testing. This is done by both parties signing a Paternity Declaration form. Parents can also sign a legal declaration, called a Stipulation, and file it with the Superior Court.

If there’s some debate over who the child’s biological father is, a DNA test is required to resolve the issue. This information is then submitted to the courts as evidence to prove the child’s paternity. The courts will examine all the evidence and then make a ruling.

Disputing a POP Declaration

What happens if parents participate in the POP program and then decide they don’t agree? According to the Alameda Department of Child Support Services, it’s possible to rescind or cancel a POP declaration. This can be done by either party within 60 days from when the original form is signed.

Since the timeline to reverse this commitment is so tight, it’s highly recommended that parents undergo DNA paternity testing if they’re not completely sure of the child’s paternity. Never sign a POP declaration if there is any doubt.
