DNA Test – Concord, California

Concord CA DNA Testing Locations

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

Concord, California – DNA Testing

Establishing paternity in Concord, CA

Establishing paternity in Concord, California, means the child will have two legal parents. It is necessary to establish parentage if the parents were not married when the child was conceived or born. Legal paternity usually gives both parents the same rights and responsibilities toward the child. Without it, you can not legally establish custody, child support, or visitation hours.

If both parents cooperate, paternity can be established at the hospital when the baby is born by signing the Voluntary Declaration of Parentage (VDP). Both parents must sign a VDP, but they should never do so if they are unsure about paternity. Parents can rely on the court to determine paternity if either party does not cooperate. The judge will likely ask the alleged father and the child to undergo a DNA test and, after that, establish paternity. The DNA test is a quick, painless, and reliable way of finding out if a man is the biological father of a child.

California woman finds her biological father with a DNA test

California woman, Dawn, had no idea that the man who raised her and was by her side her whole life was not her birth father. It took her 45 years to realize the man she considered her biological father was not her birth dad. After finding out, she did everything she could to find her biological dad and eventually reunited with him.

Dawn was inspired to become a Search Angel, someone who helps others (usually adoptees) find their families. At first, it started with helping her friend find her biological parents, and then she began volunteering. Search Angels invest their time and resources to help individuals while giving them emotional support and guidance voluntarily. She regularly helps others find their families through DNA testing.
