DNA Test – San Francisco, California

San Francisco CA DNA Testing Locations

Types of DNA Tests at our San Francisco, 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 San Francisco DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

San Francisco DNA Statistics

While San Francisco is fast becoming known for its high cost of living, there are still many people here who struggle. A typical family of three qualifies as middle class by earning over $52,000 dollars, but it sure doesn’t feel middle class, especially because of the high housing costs. In San Francisco, the median household income is $96,265 dollars.

With all the recent wealth from the tech boom, perhaps it is not a surprise that only 22 percent of kids are being raised in a single parent home, a whopping 5 percent below the national average. Nevertheless, while poverty is widely assumed to be correlated with a higher demand for DNA testing, that’s simply not the case, and San Francisco proves it. The need for paternity testing here and elsewhere cuts across all income groups and socioeconomic classes.

Real DNA Testing Stories San Francisco

We asked San Franciscans:Why Didn’t You Get a DNA Test?San Francisco Residents Said:
“The cost and I’m fairly certain of my DNA based on the way I look.”

“I don’t really know how to do one.”

“I have always thought my sister and I have different fathers. I don’t think my mom would ever want us to know if we are half siblings or not.”

About this Study: Health Street surveyed San Francisco residents about the personal side of DNA testing.

Child Custody Legalities

California tries to maintain joint physical and legal custody for children of divorced parents whenever possible. This tends to come down to the willingness of the parents to cooperate and work together to raise their children, despite the challenges of being apart. If parents cannot work out an joint custody agreement on their own, the courts must decide, and will take into account each parents’ treatment of the children in question.

Sometimes, courts will order the alleged father to get a DNA test to establish or disprove paternity. This happens in many situations, but especially if either of the parties are denying that the man in question is actually the father. There are also cases where the paternal grandparents are awarded custody, but are required to first get a DNA test to prove that their son is the actual father of the child.
