Pasadena CA DNA Testing Locations

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

Establishing Paternity in Pasadena, CA

California law presumes that when a couple is married at the time of a child’s birth, the husband is the biological father. Therefore, legal paternity is automatically established. For Pasadena, CA couples who are not married at the time of their child’s birth, California law provides multiple ways to legally establish paternity.

At the hospital following the birth of a child, both parents will be provided the opportunity to sign a Voluntary Declaration of Parentage. As long as both parties agree on the child’s biological father, paternity will legally be established at this time. If either parent is not able to sign the form at the hospital, they may also file it through a Pasadena Child Support Services office.

If a conflict arises between two parents where either the father does not agree to sign a Voluntary Declaration of Parentage or the mother claims someone else is the biological father, either parent has the ability to file a paternity case. Paternity cases can be filed through either a local Child Support Services Office or through a Los Angeles Family Court. From here, court-ordered DNA testing will most likely be ordered to effectively determine and establish paternity. Once paternity is legally established, further steps may be taken to request child support services.

Unique Laws Surround Parentage in Pasadena, CA

On January 1, 2005, California passed the Domestic Partner Rights and Responsibilities Act. Under this new law, all registered Pasadena domestic partnerships, including same-sex marriages, are provided the same rights, benefits, and legal responsibilities typically granted to a married couple. This act helped further establish parental law for those in a domestic partnership who choose to have children.

Under the enacted law, even if a child is not biologically connected to one of the parents, legal parentage is automatically granted to those who are in a registered partnership. Furthermore, even if a woman has a child before registering in a domestic partnership, the Domestic Partner Rights and Responsibilities Acts allows another individual to legally adopt the child if the mother agrees.

Experts in Pasadena, CA Say…

According to Pasadena Paternity Lawyer Carolyn Makupson, legally establishing paternity is crucial for a father seeking custodial rights over his child. Even if the mother is the primary caregiver, establishing paternity will, at a minimum, provide the father with visitation rights. Further steps may also be taken in Los Angeles Family Court in order for a father to be granted joint custody. Bear in mind, if the mother doesn’t agree to establish paternity with a man who believes he is the biological father, he will need to file a paternity action in court and submit to DNA testing.
