DNA Test – Fairfield, California

Fairfield CA DNA Testing Locations

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

Fairfield, CA – DNA Testing Information

Fairfield Man Discovers Unknown Daughter

Paul Cullen, a 76-year-old Fairfield resident, was shocked to learn he had a daughter he never knew about. The story began when two half-sisters who shared the same mother found each other online. They then each went looking for their birth fathers. It was during this search that Paul learned a one-night liaison when he was 19 years old resulted in a pregnancy. The child’s mother, who was 18 at the time, gave the baby up for adoption.

His daughter is now 55 years old. She’s a retired lieutenant colonel and a hospital administrator in Bend, Oregon. The two have reunited and they now speak to each other every week.

Voluntary Establishment of Paternity in Fairfield

Fairfield residents who wish to establish legal paternity can take advantage of Solano County’s Parentage Opportunity Program (POP) to do so at no cost. To be eligible, unmarried parents must be confident that the man is the only possible genetic father of the child. While this is a beneficial program, it’s critical that couples do not participate unless they are 100% sure about the child’s paternity. Once the declaration has been filed, neither party may request a DNA paternity test.

Reasons to Establish Paternity

According to Fairfield paternity lawyer Susan E. Christiansen, there are many important reasons to establish legal paternity. For many mothers, the prospect of being able to collect back child support and establish future child support is a compelling enough reason. Fathers may also want to ensure they’re able to get visitation rights. Establishing legal paternity will also ensure that the child is eligible for legal rights such as the ability to receive an inheritance should the father pass away.

In addition to legal and financial benefits, establishing paternity also gives a child access to both sides of their family medical history. There are also many emotional benefits a child enjoys when they have both parents in their lives.
