DNA Test – Costa Mesa, California

Costa Mesa CA DNA Testing Locations

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

DNA Information for Costa Mesa

Paternity Programs in Costa Mesa, CA

For Costa Mesa, CA residents, the state offers a Parentage Opportunity Program to assist unmarried couples with establishing legal paternity, minus the complications. To effectively establish paternity in Costa Mesa, the program allows new parents to complete a Voluntary Declaration of Paternity free of charge at the hospital following a child’s birth or through the Orange County Child Support Office.

If accepted and signed by both parents, this legal declaration declares the presumed father to be the child’s biological father. A signed document will legally bind a man to his child, providing him with paternal rights and responsibilities. Legally establishing paternity is critical to the well-being of a child as it provides the mother with the opportunity to request child support services and resources like healthcare from the father.

Determining Paternity in Costa Mesa, CA

If a mother is unsure of who her child’s biological father is at the time of birth, the last thing she should do is assume paternity and have a man who is potentially not the father complete a Voluntary Declaration of Paternity. Instead, she should file a paternity action in Orange County Family Court to properly establish paternity.

Doing so will allow a judge to request court-ordered DNA testing from the possible father to biologically match him with the child. If DNA testing results conclude that the presumed father is indeed the biological father, either parent can then move forward to request child support services, custody agreements, and visitation schedules.

Experts in Costa Mesa, CA Say…

Following the legal establishment of paternity, two parents may feud over the custodial rights of a child. Family Law Lawyer David P. Schwarz states that in California, there is a presumption that regular contact with both parents is in the best interest of the child unless otherwise shown. Due to this, joint custody agreements are highly favored by the Orange County Family Court.

If possible, before making their way to court, it’s best for both parents to sit down and construct a custody agreement of their own. Once in agreement, the two can then present their plan to an Orange County Family Court judge where he or she will assess if the plan fits the best interests of the child.
