DNA Test - Tacoma, Washington

Tacoma WA DNA Testing Locations

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

Tacoma, Washington - DNA Testing

Establishing Paternity in Tacoma, WA

When a Tacoma child is born to two unmarried parents, only the mother will obtain parental rights over the child at the time of birth. In order for the father to receive his parental rights, the state of Washington must be able to legally recognize him through written proof of paternity establishment.

To establish paternity in Tacoma, both parents can complete an Acknowledgment of Paternity at the hospital following a child's birth or through a Pierce County Family Support Division Office. This form is used to legally declare a child's paternity and must only be used if there is full confidence in a child's correct paternity or if DNA testing has been used to confirm the biological father. Failing to do so could later result in significant legal troubles if paternity disestablishment needs to take place.

Disestablishing Paternity in Tacoma, WA

In certain unfortunate situations, a previously presumed Tacoma father may discover that he is actually not the child's biological father. Due to the legal bond of a paternity establishment, the Tacoma man may still be held responsible for any legal child support obligations, regardless of him knowing that he is not the biological father; this highlights the importance of DNA testing.

In the state of Washington, a parent can withdraw a paternity acknowledgment within 60 days of filing the paternity establishment. After this deadline expires, the previously presumed father will need to challenge the paternity acknowledgment in court within four years of filing. Proof of fraud, duress, or material mistake alongside current DNA testing results is often requested to support the request for paternity disestablishment.

Experts in Tacoma, WA Say…

After two Tacoma parents have used DNA testing to accurately determine a child's father and have completed the paternity establishment process, they may also need to establish a legal custody agreement. According to Tacoma family law attorney Sands McKinley, a residential schedule and other parental rights and responsibilities are typically addressed in a court order.

Such a court order is called a "parenting plan" under Washington state law. During this process, a Tacoma Family Court will often assess both parental parties using factors such as current child-parent relationships, criminal history, and substance abuse history to create a parenting plan that works in the best interests of the child.
