DNA Test - Hayward, California

Hayward CA DNA Testing Locations

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

Hayward, California - DNA Testing

Establishing paternity in Hayward, CA

Unmarried people in Hayward, California, can establish paternity in two ways. They can sign a voluntary declaration of paternity (VDP) or get a court order. If you decide on getting the court order, you can do it yourself, or your Local Child Support Agency can help you.

The VDP must be signed voluntarily. Nobody should be forced to sign it, and the form should not be signed unless both parties are confident about the biological father. If there are doubts about who the biological father is, the mother and the alleged father usually go to court. During court proceedings, the judge will often order a DNA test. After the test, the judge can establish paternity.

Hayward, California: Benefits of establishing paternity

For children, knowing both of their parents is essential as it gives them the legal rights and privileges of both parents. Some of the main benefits are:

Financial support from both parents
Access to the medical history of both sides of the family
Medical and life insurance
Social Security and Veterans Benefits
Inheritance rights

If paternity is not established, the father does not have any legal rights toward the child, so he is unable to ask for any visitation hours or custody.

Challenging paternity in Hayward, CA

Either parent has the right to dispute parentage if the parentage has not been legally established yet. That often happens if the alleged father does not agree with paternity or if either of the parties is unsure about who the biological father is.

Laws on parentage can be complicated. Sometimes the judge can declare somebody a legal father even if the DNA test proves he is not the biological father. The judge looks after the child's best interests and may consider other factors when determining paternity.
