DNA Testing El Cajon CA

El Cajon CA DNA Testing Locations

Types of DNA Tests at our El Cajon CA clinics:

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

El Cajon, California - DNA Testing

Paternity Programs in El Cajon, CA

When two unmarried El Cajon parents have a child, both parents will need to establish paternity for the biological father to gain parental responsibilities and rights over his child. Fortunately, this process is made easy through the San Diego County Paternity Opportunity Program (POP), where parents can establish paternity free of charge.

To establish paternity, the program asks the two El Cajon parents to complete a Voluntary Declaration of Paternity, which is used to declare and identify the child's biological father. However, it's important to remember that this process is legally binding, and a parent should confirm the assumed paternity is 100% accurate first. Confirmation can be completed through DNA paternity testing services.

Dealing with a Difficult Paternity Establishment in El Cajon, CA

While San Diego County's POP is a simple and easy way to establish paternity, it is a voluntary process, and a parent does have the ability to refuse to sign the appropriate paperwork. In the event that a parent refuses to sign a paternity acknowledgment out of disbelief in a child's paternity, it's highly recommended that the parent seeks the assistance of the San Diego County Family Court.

Submitting a petition to establish paternity allows the state of California to mandate that the opposing parent appears in court to complete the necessary steps to establish paternity. This process will typically require the completion of DNA testing to identify the child's biological father. If properly identified, the courts can then establish paternity as well as child custody and support agreements if necessary.

Disputing Paternity in El Cajon, CA

In certain paternity cases, two El Cajon parents may be quick to establish paternity without the use of DNA paternity testing, just to learn that the presumed father is actually not the biological one at a later date. This realization can be frustrating, especially if monthly child support arrangements have already been made, and it can be even more difficult in court to remove them.

Signifying the importance of DNA paternity testing, an El Cajon Parent has only up to 60 days following a paternity establishment to dispute parentage under California law. After this 60-day mark, the individual will be required to seek legal assistance and demonstrate to the San Diego County Courts proof of incorrect paternity.
