DNA Test - Cerritos, California

Cerritos CA DNA Testing Locations

Types of DNA Tests at our Cerritos, 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

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 Cerritos DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Cerritos CA DNA and Paternity Testing

Top Reasons to Establish Paternity

When a child is born to parents who aren't married, he or she won't have a legal father until someone takes steps to establish paternity. While this does require some effort, it's well worth it. According to Los Angeles County paternity attorneys at The Law Offices of Karen S. Brown, there are many important reasons to establish paternity. This includes ensuring the child receives financial support from both parents and giving the child access to the father's health coverage.

Once paternity is established, the child can also receive an inheritance from the father and may be eligible for Veterans and/or Social Security benefits based on the father's records. In addition, the father can stay involved in the child's life by requesting visitation and/or custody.

Establishing Paternity in California

There are two primary ways to establish paternity in California:

1. Voluntary Declaration

If both parents agree about the child's paternity, they can sign and file a Voluntary Declaration of Paternity through the state's Paternity Opportunity Program (POP). Once this form is processed, the father's name will also be added to the child's birth certificate.

2. Court Order

When there's a paternity dispute, an interested party may need to file for a court order with the County Court Clerk. In this case, prior to making a decision, the courts are likely to require a DNA test to determine whether the man is the child's biological father.

LA County Case Highlights Complexity of Paternity Presumptions

A Los Angeles County court case highlights the complexity of the state's "presumption of paternity" rules. It began when a woman had a relationship with a man named Christopher and learned she was pregnant after the relationship ended. She told the man he was the child's father but began dating another man, named Colin. When she had the baby, Christopher came to the hospital, but only saw the baby two times after that.

The mother moved in with Colin and the child began calling him "Daddy." Eventually, LA County took legal action against Christopher, saying he should pay $1,420/mo. in child support. Christopher denied he was the child's father and said Colin was the child's "presumed father" because he "held the child out as his own." A DNA test found that Christopher was the child's biological father, but the judge ruled that Colin was the child's legal father. However, an appeals court reversed this, holding the child's biological father responsible for his financial support.
