DNA Test - Chino, California

Chino CA DNA Testing Locations

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

Chino, California - DNA Testing

Establishing paternity in Chino, CA

If unmarried parents in Chino, California, want their children to have the same benefits as children born to married parents, they must establish parentage. Signing a Voluntary Declaration of Parentage (VDP) is the quickest and easiest way to establish parentage in Chino. However, this should only be done if both parents agree. Once this document is signed and filed, it has the same legal value as a court order.

Parents who are unsure or disagree about who the parents are may go to court. In some cases, the judge will order the alleged father and the child to undergo a DNA test. DNA tests are usually performed with a quick, painless cheek swab that can prove paternity with high accuracy. Establishing paternity does not establish custody, visitation hours, or child support; those need to be established separately, but it is only possible once legal parentage has been determined.

Chino, California: Disputing parentage in Chino, California

Sometimes, a man can be told he is a father of a child, and he may disagree. If paternity has not been established yet, he has every right to dispute it. In most cases, a DNA test will be done on the alleged father and the child to determine whether there is a child-father relationship. In same-sex partnerships, if the woman served with Petition to Establish Parental Relationship did not intend to be the child's second mother, she can also dispute it.

Parentage laws can be complicated. Sometimes, it may be too late if the court has decided someone is the legal father and the mother wants genetic testing. The same can happen if the paternity has been established and the man finds out he is not the birth father. People often involve a family law facilitator, who can help them determine the best solution based on their specific situation.
