DNA Test - Vista, California

Vista CA DNA Testing Locations

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

Vista, California - DNA Testing

Establishing paternity in Vista, California

In Vista, California, establishing paternity means signing a Voluntary Declaration of Paternity (VDP) or getting a court order that says who the child's legal parents are. Establishing paternity is necessary unless the parents are married. After establishing paternity, parents will usually share rights and responsibilities, and the child can receive benefits that would not otherwise be available.

If both parents are sure about the biological father, they usually sign a declaration of parentage. Often, parents can sign it at the hospital just after the child is born.

However, there are situations when either party disagrees with paternity. In that case, they can go to court and let the judge decide about paternity. The court hearing usually involves DNA testing to prove whether the alleged father and the child are related. A simple cheek swab can determine their relationship, and the judge can decide whether to establish paternity after considering the DNA results.

Vista, CA: Disputing parentage

When a man is told he is the biological father but disagrees, he can always schedule DNA testing. DNA testing is done to compare the father's and child's DNA, and experts compare genetic markers to determine if there is a relationship between them. The alleged father and child can do these tests at home using an at-home DNA testing kit, but it is important to note that these results are not usually admissible as evidence in a court of law. If Vista parents intend to dispute parentage using the DNA results, it is better to register for a legal DNA test at a certified clinic.

If paternity has already been established, but the father has doubts, challenging paternity in Vista can be much more complicated. In these cases, many people seek the help of a family lawyer.
