Paternity Testing in Oceanside CA

There are several types of DNA testing services that are offered at our Oceanside testing centers to validate close family relationships. The most commonly ordered DNA test is a legal paternity test to conclusively establish whether or not a man is the biological father of a child. Health Street's 21 marker DNA paternity testing is the state of the art. Our paternity test results are statistically conclusive at the rate of 99.9% or greater.

Other DNA Tests

Relationship Tests to validate grandparent to grandchild, siblings, half-siblings, aunts, and uncles:

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)

DNA tests such as sibling or avuncular studies, can sometimes come back with a result of less than 95% certainty. This is normal, especially if only two parties participate in the test. Adding an additional close relative to the test helps us learn more about the family's DNA composition and typically leads to a more conclusive result.

Specimens we can test for DNA

The easiest and most reliable way to perform a genetic sample collection for a paternity test is by a swab of the inner cheeks. These skin cells, known as buccal cells, rub off easily onto cotton swabs and remain in place, to be extracted by our testing laboratories for analysis.

Other specimens, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also undergo lab testing to see if there is a match. These non-standard DNA tests are done by registering online for an Alternative Specimen DNA Test (Nails, Teeth, Fabric). Once registered, you ship the DNA sample to our lab. We'll attempt to extract the DNA and compare it to a cheek swab of the other party.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

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 to hold up in court, the DNA specimen must be collected at a clinic using strict chain of custody procedures. The DNA testing technicians at our Oceanside test centers are trained to follow guidelines that ensure that the results can be used for legal purposes.

The results of our legal DNA tests can be used for any legal purpose:

to change the name on a birth certificate
to petition for child support
to petition for survivor benefits
for child custody arrangements
to alter inheritance procedures or wills

Home tests offer more flexibility:

Home DNA tests are specimens containing DNA (or possible DNA) that are shipped to us for analysis. The results of these home tests cannot be used in court (since there is no way to prove whose specimens were actually sent). However, the tests are just as accurate and can provide peace of mind. At-home DNA tests also offer a lot more flexibility.

In addition to commonly mailed in DNA specimens like hair follicles, we can also extract DNA from other bodily fluids. We can even try and lift the DNA left on items like clothing, a toothbrush, or a straw. If we can get the DNA from the alternative item, we can then compare it to another person to see if they are related. Some examples include:

Stained garments
Mucus and other bodily fluids
Soda cans
Chewing gum

How to schedule a DNA Test in Oceanside CA

Scheduling a DNA test at one of our Oceanside clinics is simple and fast, and we often have appointments available in the same week, though it's always helpful to schedule in advance to make sure you get the time you want. We have clinics in Oceanside, plus many more throughout California and across the United States. During registration, we'll show you the nearest locations so you can choose the one that's most convenient. You'll pick the times and days that you prefer.

You can set up separate appointments for each of the people being tested, either at the same location or at different locations. You'll get an email and text message with your appointment information. There is no fee if you need to change the time or location of a DNA test appointment at any time.

How long it takes to get results of a DNA test

Paternity tests conducted at one of our Oceanside facilities typically take about a week to come back. Other relationship tests, such as sibling studies, can take a few days longer to come back. When the results are ready, you are notified immediately via email. Then, the hard copies of the paperwork are sent afterward via regular mail.

The DNA test appointment - what to expect and what to bring

The appointment itself only takes about 15 minutes. The specimen collection process is a simple and painless cheek swab. No needles are used. When you're being tested at our Oceanside clinic, you'll be asked to provide fingerprints and to show photo identification. We'll also take pictures of the people being tested so that the final report will include legal assurances of who was actually tested.

For infants, hospital discharge papers qualify as identification. Otherwise, a birth certificate or social security card can be used as ID for a child. No other preparations are required for this appointment.

Does the mother need to be present at a paternity test?

If a man is considered the legal father of a child, then the mother does not have to be present or give consent for paternity testing. However, if he is not currently considered the legal father, then he cannot sign for the child. Therefore, the mother does need to be there. If neither parent is available, other legal guardians can bring the child so long as they have the right to make medical decisions on the child's behalf.

DNA testing if one party is not in Oceanside

The two parties testing (for example: father and child) do not have to be tested at the same time or even at the same location. We have many clinics across California as well as nationwide, so we can test one party in Oceanside and the other party anywhere else in the USA. The specimens are then matched up in the lab for analysis.

Laboratory certifications

Health Street works strictly with AABB Certified labs for DNA testing. All specimens that are collected in Oceanside or elsewhere are shipped securely from our testing locations to a nationally certified laboratory.

Proving Paternity for Child Custody Purposes in Oceanside, CA

In Oceanside, CA, unmarried parents must establish paternity to give the child a legal father. This can be done voluntarily by signing an Acknowledgement of Paternity if both parents agree. If the parents disagree or question who the biological father is, they can have the court establish paternity. In paternity cases, judges often order paternity testing to prove paternity. Once paternity is established, the child has a legal father, and the judge can issue custody, visitation, and child support orders.

The Importance of Lab DNA Testing in an Oceanside Paternity Court Case

If an unmarried Oceanside, CA parent finds they need to legally establish the child's paternity to request child support payments or to ask for visitation rights or custody, they should know that at-home DNA testing kits do not hold up in court as well as DNA tests that are conducted by a certified laboratory. Especially if the parents disagree about the biological father of the child, it is critical that the DNA test results are irrefutable.

San Diego County, where Oceanside is located, provides comprehensive support services for married and unmarried parents. The Department of Child Support Services provides information for those seeking child support, plus information about their Paternity Opportunity Program (POP) for unmarried parents. The San Diego County Superior Court of California's Family Support Division tells Oceanside and San Diego County parents how to legally establish paternity and request child support.

Experts Say...

Palmer Rodak & Associates, law attorneys in Oceanside, CA, explain the importance of establishing paternity by saying, "There are numerous reasons why it is important for fathers who are not married to establish paternity so they can protect their unwed fathers' rights." He explains that establishing paternity provides unmarried parents with the same rights as married parents. "These include being able to have life and health insurance coverage through either parent, the right to receive veteran's and social security benefits, and the right to inherit from both parents," the law firm says. "Furthermore, paternity enables children to receive financial support from both parents, married or unmarried."
