DNA Test - Lancaster, California

Lancaster CA DNA Testing Locations

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

Lancaster, California - DNA Testing

Establishing paternity in Lancaster, CA

In California, parents can establish paternity in two ways. They can either sign a Voluntary Declaration of Paternity or get a court order. If both parents sign the voluntary agreement, they are considered legal parents, but they must file this form with the California Department of Child Support Services to make it effective.

If parents do not agree on paternity or do not want to sign the declaration, they can go to court and let the judge decide who the legal father is. Court proceedings will often require the alleged father and the child to take a DNA test. Based on the DNA test results, the judge can establish paternity.

Lancaster, California: Challenging paternity

Sometimes, either parent is unsure about the parentage; in that case, they can request DNA testing to find out who the biological father is. Children always inherit DNA coding from the mother and father. Therefore, if the child and the alleged father do genetic testing, they can quickly establish a parental relationship. Samples can be easily taken by cheek swab.

However, be careful before you decide on a DNA test. If you take the test home, the court will not accept it. It may be the easiest to go to the court and let the court order genetic testing. Once the judge has the results back, they can establish paternity.

Establishing paternity has many benefits for children, such as knowing both parents, getting financial support from both parents, having access to the medical history from both sides of the family, health and life insurance, and possible rights to inheritance from either parent. Sometimes, there can also be veterans' benefits or social security.

Children are not the only ones who can benefit from establishing paternity. The father can gain the same rights and responsibilities as a mother, and once paternity is established, the court can also establish visitation hours or custody.
