DNA Test - Lodi, California

Lodi CA DNA Testing Locations

Types of DNA Tests at our Lodi, 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.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Lodi DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Paternity Programs in Lodi, CA

Through the San Joaquin County Department of Child Support Services, Lodi parents who are not married at the time of their child's birth can use the Parentage Opportunity Program (POP) to establish paternity. Establishing paternity is extremely important for recent unmarried parents, as it is used to declare a child's legal father, have his name placed on the birth certificate, and grant him parental rights and responsibilities.

Through this program, two Lodi parents can establish paternity by submitting a Declaration of Parentage form. Following the child's birth, a hospital or clinic representative will present this form for completion. However, this form should only be signed if both parents have full confidence in the presumed father. In the event that more than one man could potentially be the biological father, it's important to first seek DNA testing prior to establishing paternity to avoid legal concerns later on.

Benefits of Establishing Paternity in Lodi, CA

The benefits of establishing paternity go beyond providing an unmarried Lodi father with parental rights and responsibilities. For instance, if a mother must request monthly child support payments from a father, San Joaquin Child Support Services will first require a proper establishment of paternity. Likewise, establishing paternity will benefit a child, since having two legal guardians will expand access to resources, such as health insurance coverage, inheritance, and social security benefits.

Canceling a Paternity Establishment in Lodi, CA

In certain paternity establishment cases, two Lodi parents may be quick to sign and submit a Declaration of Parentage without confirming the given paternity claim through DNA testing. If a parent learns later on that the previously presumed father is actually not the biological father, they will need to seek the assistance of San Joaquin County Family Courts to rescind the establishment.

If this new discovery is made within 60 days of the filing of the form, and no court order for custody, visitation, or child support has been made, a parent can submit a Declaration of Paternity Rescission form. After this 60-day mark, a parent will need to file a motion in court to remove the establishment, which will likely require the use of DNA paternity testing to accurately identify the biological father.
