DNA Test - San Jose, California

San Jose CA DNA Testing Locations

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

Establishing paternity in San Jose, California

Parentage is the recognition of a parent's legal relationship with children. The court can establish it, or an easier way is The Parentage Opportunity Program, which is free of charge and decreases the time and money spent on the court process.

All parents need to do is file a Voluntary Declaration of Parentage which has the same force as an order issued by the court. This form is eligible for unmarried couples, who are sure there is only one possible genetic father, or for those who had their child through assisted reproduction using sperm/egg donation—except if any donation was from their spouse.

Challenging paternity in San Jose, CA

If an individual is unsure whether he is or is not the father of a child, a petition can be filed to the court. In most cases, if the parentage was not established yet, either parent can dispute it.

If, for example, a man wants to dispute his paternity to a child, the court will probably ask him to do a DNA test to show whether he is or is not a biological father. If there is a case for a same-sex couple, a woman who was served with a Petition to Establish Parental Relationship can dispute it if she did not intend to be the child's other parent.

San Jose, California: Benefits of establishing paternity

There are multiple reasons why establishing paternity can be beneficial not only for the child but also for the mother and the father.

Thanks to establishing paternity, the child will have access to the father's medical history, learn more about the family history, help with finding the child's identity, and help pave the way for a solid child-father relationship. The child will have access to medical insurance, life insurance, and other benefits.

There are also benefits for the mother, like sharing parental responsibilities and the costs of raising a child. They can also share custody and plan visitation. The mother can seek out child support as well.

Establishing paternity should also be important to the father because it gains him legal rights to the child. He can participate in life and be eligible for custody or parenting time.
