DNA Test - Pasadena, California

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.

How to Establish Paternity in Pasadena, CA

Pasadena parents who are not married at the time of a child's birth must take the necessary steps to establish paternity in California. Legal paternity grants a Pasadena father paternal rights over his child as well as the right to place his name on the birth certificate. The legal establishment of paternity is also required if either Pasadena parent wishes to seek child support services.

Pasadena parents can establish paternity by signing a Voluntary Declaration of Parentage via the California Parentage Opportunity Program (POP). This completely voluntary establishment process can be completed at the hospital following the child's birth or at a later date through a Pasadena Child Support Services office. If either Pasadena parent has a reasonable doubt about a child's paternity, be sure to first seek DNA paternity testing before moving forward with this process.

Laws and Regulations Surrounding Paternity in Pasadena, CA

Under the Domestic Partner Rights and Responsibilities Act, Pasadena parents who are in a domestic partnership, such as same-sex marriage, are granted the same rights and responsibilities that are provided automatically to married couples. Because of this Act, Pasadena couples who choose to have children have better clarification on how paternity establishments will work.

According to the Domestic Partner Rights and Responsibilities Act, when a child is not biologically connected to a parent but the two are in a registered domestic partnership, legal parentage will automatically be granted to both parents regardless of biological status. If a Pasadena resident has a child before registering as a domestic partnership, the law will allow the spouse to adopt the child and establish legal parentage if the mother approves.

Seeking Paternity Establishment Assistance in Pasadena, CA

When one parent refuses to establish paternity in the state of California, the other Pasadena parent will not be able to request child support services from the opposing parental party. In the event that one parent refuses to establish paternity for any sort of reason, the other must file a paternity petition through a Los Angeles County Family Court.

A paternity petition allows a judge to mandate that DNA paternity testing is completed by the presumed parent to establish paternity. When the biological father is accurately identified, paternity can be established as well as child support agreements.
