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.

Benefits of establishing paternity in San Francisco, CA

Married couples generally do not need to establish paternity since the law usually considers the husband the biological father. However, if the couple is not married, they can sign a Voluntary Declaration of Parentage before leaving the hospital with their child. If one parent is unsure of paternity, the court will usually order a DNA test, which a certified lab will perform for each party. At-home DNA test kits results are not court-admissible proof of paternity.

Establishing paternity has multiple benefits, such as:

Financial support from both parents
Legal documentation of the child's parents
Child's access to family medical records
If available, there may be medical and life insurance coverage from the parent or inheritance
In some cases, the child may be eligible for Veterans and Social Security benefits

San Francisco, CA: Challenging paternity

Sometimes, either party may not be sure who the father is; in this case, the best option is to take a DNA test. A court order for genetic testing can determine the biological father. If the genetic testing results are disputed, the matter will be set for a hearing or a trial. The court will then establish the parentage.

A man reunited with his family thanks to a DNA test

Matthew Robertson was adopted as a child, but then his adoptive mother died when he was only six years old. This left a scar on his heart. Years went by, and eventually, he decided to take a DNA test to find his biological mother. Matthew finally found his birth mother at the age of 49, and feels like he finally filled the gap in his life. In addition to his mother, he also found three siblings!

When he contacted the woman on social media, she replied and confirmed she was indeed his mother but said she needed time. Eventually, they shared an emotional call and then met to spend the weekend together. He said that by the end of the weekend, they could not stop hugging each other, and they had already planned another trip. Now, they are in touch all the time and are thankful for the DNA test that reconnected them.
