DNA Test - Lake Forest, California

Lake Forest CA DNA Testing Locations

Types of DNA Tests at our Lake Forest, 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 Lake Forest DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Lake Forest, California - DNA Testing

Establishing paternity in Lake Forest, California

Parents who are married when their child is born in Lake Forest do not need to take any additional steps to establish paternity, as California law automatically considers the husband to be the child's legal father. Unmarried parents, however, will need to establish parentage. The most common way to establish parentage in California is by signing a Voluntary Declaration of Parentage (VDP). This document is often available at the hospital, so parents who are in agreement can sign it right after the child is born. After the VDP is signed and filed, both parents' names can be added to the child's birth certificate, and both will be considered legal parents.

If the alleged parents disagree about who the legal parents should be, they often go to court. Sometimes, the judge will order paternity testing for Lake Forest fathers. In this case, the alleged father and the child will receive a quick and painless cheek swab to collect buccal cells, which is then tested at the laboratory. After paternity has been established, the judge can also determine child support, custody, or visitation hours if necessary.

Lake Forest, CA: Disputing parentage

If paternity has not yet been established, it can be easier for a parent to dispute parentage. For example, a man may be informed that he is the birth father, but he does not believe this to be true. In that case, he can request a DNA test to prove whether he is the biological father.

Parentage can also be disputed in same-sex relationships. For example, if a woman was served with the Petition to Establish Parental Relationship but never intended to be the child's other mother, she can dispute it.

Depending on the situation, disputing parentage in Lake Forest, California can be challenging, and paternity laws are very complex. Many people contact a family law facilitator to help guide them through the process of establishing parentage.
