Types of DNA Tests at our Fontana, California clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

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 Fontana DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Fontana, CA - DNA Testing

Establishing Paternity in Fontana, CA

California Family Code Section 7540 states that if two parents are married when the child is born, the husband is the legal father, and the wife is the child's legal mother. Registered domestic partners in Fontana have a legal presumption of parentage, according to California Assembly Bill 205. However, if the parents are not married when the child is born, they must establish paternity for the child to have a legal father.

Experts Say...

Wallin & Klarich, family law attorneys serving Fontana and San Bernardino County, explain how a child benefits from established paternity. "When paternity is established, the child would attain certain rights and privileges," the law firm states. These benefits include financial support and inheritance from both parents, social security, workers' compensation, and other available benefits. "The benefits to the child in paternity cases go beyond the legal aspects," the firm continues. "When it is determined who the parents of the child are, the child would receive an emotional benefit of knowing who his or her parents are."

Proving Paternity for Child Custody Purposes in Fontana, CA

In Fontana, CA, unmarried parents must establish paternity for custody, visitation, and child support orders to be issued by the court. If either parent has doubts about who the child's biological father is, the court may order DNA testing to prove paternity, or either party may request DNA testing.

Once DNA testing confirms paternity, a judge can grant an order stating the legal parents of the child, and paternity is established. In some cases, a court case can be avoided if both parents agree to sign a Declaration of Parentage, which is a legally binding form claiming they are the child's parents. In Fontana, a child's legal parents must provide financial support.
