Napa CA DNA Testing Locations

Types of DNA Tests at our Napa, California locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

Establishing paternity in Napa, CA

Establishing paternity is an essential aspect of parenting in Napa, CA, and one that cannot be overlooked. While it may not be necessary to establish paternity if parents are married, unmarried individuals should do so if they have children. The Voluntary Declaration of Paternity (VDP) is one way to establish paternity if the biological father is known. It can be signed at the hospital once the baby is born, with assistance from the staff.

However, going to a local child support agency or court is another option for establishing paternity. In court, the judge may order a DNA test for the alleged father and the child to determine paternity. This method can provide concrete evidence of paternity, which can be used to establish important factors like custody, visitation hours, and child support.

Napa, California: Benefits of establishing paternity

Establishing paternity in Napa, California has numerous benefits for both parents and children. Once paternity is established, both parents can have equal rights and responsibilities towards the child, including financial support and decision-making. The child also benefits from having access to family medical history, emotional and financial support from both parents, and the right to inherit.

Additionally, being listed on a birth certificate provides access to Social Security, health and life insurance coverage, and veterans and disability benefits if applicable. Therefore, it is crucial to establish paternity to ensure the best outcomes for all parties involved. DNA testing is an excellent way to do this, and our DNA tests are an accurate and reliable option for establishing paternity.
