DNA Test - Palm Desert, California

Palm Desert CA DNA Testing Locations

Types of DNA Tests at our Palm Desert, California clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

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 alleged father and child or children. 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 ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. 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. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Palm Desert DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Palm Desert, CA DNA Testing

What Are DNA Tests Used For?

Services for DNA testing in Palm Desert, CA, can be used for paternity confirmation, child custody arrangements, changes to birth certificate, and post-mortem analysis for inheritance claims. Learn more about DNA testing and its use below.

Paternity Testing

If parents are unwed and unsure about paternity, they can order a DNA test to find highly reliable answers. Paternity testing is also often ordered by a judge if parents are establishing paternity via court proceedings.

Child Custody and Support

Legal paternity must be determined before parents can establish child custody and support. DNA testing eliminates doubts regarding the child-father relationship, showing test results with 99.99% certainty.

Changing a Birth Certificate

Instances where the legal father is discovered not to be the biological father may mean that changes to the birth certificate are needed. DNA testing is crucial for accurately documenting the biological father's identity, and parents sometimes opt to take DNA tests to prove mistaken paternity.

Post-Mortem Testing

Post-mortem DNA testing can establish a biological relationship with a deceased individual, which is required for Social Security benefits or inheritance claims.

How DNA Tests Are Analyzed

DNA samples are analyzed by professionals in AABB-certified laboratories, comparing at least 21 genetic markers to determine the probability of biological relation between individuals.

How Long Does It Take to Receive DNA Test Results?

The time for receiving DNA test results can differ based on the type of DNA samples provided.

  1. Cheek swab tests typically provide results within one week.
  2. Hair follicle DNA tests or other alternative methods can take up to two weeks for results.

Establishing Paternity in California

There are two main ways of determining paternity in California. Parents can establish it by signing the Voluntary Declaration of Parentage (VDOP). They can sign it at the hospital after the baby is born, and then they must file the form with the state.

Another option for establishing paternity is going to court. In cases of uncertainty or dispute, the judge may order DNA testing to determine paternity. It's important to note that the judge can establish someone as a legal father even if he is not genetically related, as many other factors are also considered in these cases.
