DNA Test - Whittier, California

Whittier CA DNA Testing Locations

Types of DNA Tests at our Whittier, California locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Whittier DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Whittier, California - DNA Testing

Establishing Paternity in Whittier

In the state of California, there are three primary ways to establish a child's legal paternity. According to the Whittier-based ABA Family Law Firm, the parent's relationship at the time of the conception is a primary factor in the process. If the parents are married and "cohabitating" at the time, the mother's husband is presumed to be the child's legal father. This presumption of paternity can be rebutted with a court-ordered DNA test; however, the test must be requested within the first two years of the child's life.

Unmarried parents can either complete a voluntary acknowledgment of paternity or petition the courts to establish legal paternity. The courts will typically order a DNA paternity test prior to issuing a ruling.

California's Parentage Opportunity Program

A child's legal paternity, also known as "parentage" can be easily established through the state's Parentage Opportunity Program (POP). This allows eligible parents to complete and file a form, which has the same effect and force as a judgment for parentage that has been issued by the courts. To be eligible, unmarried parents must feel confident that the man is the child's only possible biological father. If there is any question regarding the identity of the child's father, the POP program does not apply, and a court-ordered DNA test is needed.

The voluntary acknowledgment of paternity form can be completed at the hospital when the child is born, at the local child support agency office, at offices of local registrars of births and deaths (vital records), or at county welfare departments. The forms can also be filed with the family law facilitator at the county courthouse, which, for Whittier residents, is located at 7339 S. Painter Ave., Rm 300 Whittier, CA 90602.

Suing for Paternity in Whittier

When the presumption of paternity or the POP does not apply, an interested party who wants to establish paternity must file a petition with the court system. According to Whittier-area family law attorneys with the Fernandez & Karney law firm, a paternity lawsuit can be filed before a child is born. Only certain parties have "standing" to request a legal DNA test and a court-ordered paternity ruling. This includes the mother, the mother's husband, a man who believes he is the child's father, the local child support agency, or the child themselves if they are over the age of 12.
