DNA Test - Simi Valley, California

Simi Valley CA DNA Testing Locations

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

Simi Valley, California - DNA Testing

Establishing paternity in Simi Valley, California

If parents are unwed when the child is born or conceived, the father has no legal rights unless he establishes paternity. The same applies to same-sex parenting. For example, if two unmarried women want to co-parent a child, and the woman who did not give birth would like to become a legal parent, these parents would have to legally establish parentage.

In Simi Valley, California, parents can establish paternity by signing a Voluntary Declaration of Parentage (VDOP) or by court order. When parents go to court, the judge often requires a DNA test to determine if the alleged father is the biological father. After the DNA testing results have returned, the judge can establish. However, for same-sex relationships, it is best if the parents talk to the family law facilitator because paternity law is quite complex.

Parents must establish paternity before they can legally establish visitation hours, custody, or child support through the court.

Challenging paternity in Simi Valley, CA

Sometimes, people are unsure about paternity. DNA testing can easily determine whether the alleged father is the birth father with up to 99.9% accuracy. Most commonly, a cheek swab from the father and the child is used to collect DNA specimens, which a certified lab then examines to determine how much DNA coding is shared. Based on the DNA results, paternity can be established by the court.

Please keep in mind that home DNA test results usually are not accepted as court-admissible evidence for paternity. While the results are just as accurate as professional clinic DNA test results, home DNA tests are intended for people who are just looking for peace of mind.
