DNA Test - Yucaipa, California

Yucaipa CA DNA Testing Locations

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

Yucaipa, CA DNA Testing

What Are DNA Tests Used For?

DNA testing in Yucaipa, California, can be used for both personal and legal reasons. Common uses include the following.

Paternity Testing

This is a primary reason for DNA testing. Whether a mother is uncertain about the child's biological father, or a man is unsure if he is the biological father, DNA testing offers clarity and peace of mind.

Child Custody and Support

In cases where a child is born outside of marriage, establishing paternity is essential for determining custody rights and child support obligations. Courts often require DNA tests to confirm the biological father.

Changing a Birth Certificate

Sometimes, parents may voluntarily establish paternity without taking a DNA test and learn later on the legal father is not the biological father. DNA testing can prove mistaken paternity and be used to help correct the birth certificate.

Post-Mortem Testing

This type of testing is crucial for establishing familial connections with a deceased individual, particularly in inheritance cases.

How DNA Tests Are Analyzed

DNA samples are typically analyzed in certified laboratories, where technicians compare 21 genetic markers between specimens to determine a biological relationship. Sample types often include cheek swabs or hair follicles.

How Long Does It Take to Receive DNA Test Results?

The wait times to receive DNA test results in Yucaipa, CA, depend on what kind of sample was taken during DNA collection.

  1. Cheek swab tests: Results are generally available within a week of sample collection.
  2. Hair follicle tests: DNA test results using hair follicles may take more than one week.

Establishing Paternity in California

Parents from California have two options for establishing paternity if they are unmarried:

  1. They can sign a form called a Voluntary Declaration of Parentage and file it with the state (often done at the hospital once the baby is born) or
  2. They can go to court and let the judge determine paternity, which usually means the judge will order DNA tests to prove paternity. Parents can open a case to establish paternity or ask a local child support agency to start the case.
