DNA Test - Orange, California

Orange CA DNA Testing Locations

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

Orange, California - DNA Testing

Experts Say...

The Law Offices of Lisa R. McCall, serving Orange, CA and Orange County, say that fathers who are not married to the mother of their child may need to go through California's parentage process to ensure legal rights to the child. "Establishing parentage means that there is a legal order that determines the paternity of a child," explains the firm, "Without establishing paternity legally (parentage), the mother will have no legal right to require the father to financially support his child." The law firm also explains that if a father does not admit he's the father or does not believe he's the biological father, DNA testing may be necessary to prove paternity.

Proving Paternity for Child Custody Purposes in Orange, CA

In Orange, CA, paternity (parentage) must be established for all fathers that are not married to the mother at the time of birth or conception, even if he can prove he is the biological father. Paternity must be established before the judge can issue child support, visitation, or custody orders. If a father does not think he's the biological father or if he denies fatherhood, the court may order DNA testing. Once the DNA test confirms paternity, paternity can be established, and the father has legal rights to the child.

Importance of Establishing Paternity

Establishing paternity is important for the child to have the emotional benefit of knowing both parents and for the child to receive the same benefits as children born to married parents. Once paternity is established, the child can access benefits, such as financial assistance from both parents, legal documentation, and access to both parents' medical records, life insurance coverage, medical insurance, social security, veteran's benefits, and inheritance. Fathers benefit from establishing paternity by obtaining legal rights to the child, visitation, and custody, and mothers receive financial assistance from the father.

In Orange, CA, paternity can be established by signing a Voluntary Declaration of Parentage or through the court.
