DNA Test - Torrance, California

Torrance CA DNA Testing Locations

Types of DNA Tests at our Torrance, 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 Torrance DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Establishing Paternity in Torrance, CA

When a child is born to two married Torrance parents, no additional steps will need to be taken to establish paternity as California law automatically presumes the husband to be the child's biological father. However, if the two parents are not married, only the mother will possess rights over the child and paternity must be legally established for the father to receive parental rights.

Establishing paternity is an important process as it legally declares the identity of a child's biological father, grants him paternal rights, and allows his name to be placed on the child's birth certificate. Not to mention, establishing paternity enables either parent to seek monthly child support services as well as any custody or visitation agreement if necessary.

Assistance Establishing Paternity in Torrance, CA

In efforts to encourage paternity establishment across the state of California, state officials developed the Parentage Opportunity Program. This program creates a simple, cost-free method to establish paternity via a Voluntary Declaration of Parentage form. This form should be completed by both Torrance parents in a timely manner to streamline any child support or custody hearings.

However, if there is any doubt in a child's paternity, the mother and presumed father must first seek DNA testing services prior to establishing paternity. If either parent refuses to undergo DNA testing to properly establish paternity, they can file a petition through Los Angles Family Court to initiate the establishment process via court order.

Experts in Torrance, CA Say…

Following the paternity establishment process, two Torrance parents may require the assistance of the Los Angeles Family Court to establish a custody agreement. According to Torrance family law attorney Colleen Barberis, the courts will consider numerous factors to develop a custody agreement that works in the best interests of the child. These factors may include a history of domestic violence, substance abuse, and poor living conditions.
