DNA Test - Placentia, California

Placentia CA DNA Testing Locations

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

Placentia, CA DNA Testing

What Are DNA Tests Used For?

Did you know that DNA testing can be used to change birth certificates, establish paternity, or determine custody and child support? In some cases, people also need to do post-mortem testing to establish relationships with deceased individuals.

Paternity Testing

Parents may find themselves in situations when they have a baby but are unsure about paternity. The mother may have been in an intimate relationship with more than one man at the time when the child was conceived, or the alleged father may be doubting his biological relationship with the child. The man and the child can take a DNA test to ensure the legal father is the birth father.

Child Custody and Support

If you need to establish child support and custody in Placentia, CA, paternity must be established first. If parents choose to determine paternity by court order, the judge often orders DNA testing to prove paternity before they establish custody, visitation hours, and child support.

Changing a Birth Certificate

DNA testing is used when there's a need to amend a birth certificate, especially if it's discovered that the legal father is not the biological father.

Post-Mortem Testing

Post-mortem testing may be needed if an individual has passed and someone, usually children, wants to establish a biological relationship. This is often used for inheritance claims or accessing Social Security benefits.

How DNA Tests Are Analyzed

DNA samples are analyzed in our certified laboratories. Technicians compare 21 genetic markers to confirm biological relationships. Cheek swabs are commonly used for sample collection, but hair follicles can also be used.

How Long Does It Take to Receive DNA Test Results?

It can take up to two weeks to receive DNA test results, depending on the type of DNA sample you provided.

If hair follicles were used for DNA testing, the results can take a little longer but are usually available by two weeks.
If you did a cheek swab, the results should be available a week after the sample was collected.

Establishing Paternity in California

Unmarried parents in Placentia, California, should establish paternity if they do not want their child to miss out on multiple benefits and if they're going to share rights and responsibilities. They have two options to determine paternity:

They can sign a form called Voluntary Declaration of Parentage, which is often done at the hospital after the baby is born with the help of the staff or
They can go to court and let the judge determine paternity. In that case, the alleged father and the child may have to undergo genetic testing to prove their relationship.
