DNA Test - Spokane Valley, Washington

Spokane Valley WA DNA Testing Locations

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

Spokane Valley, Washington - DNA Testing

DNA Test Reunites Brothers in Spokane After 51 Years

Nick Nickelson and Dave Johnson are brothers with many similarities, but for 51 years, they had never met. Johnson, who was three when Nickelson was born, knew he had a younger brother and had begun a search 15 years prior. The two were reunited after Nickelson took a DNA test to find out more about his ancestry and Johnson took one hoping to find his long-lost brother. When the tests revealed their relationship, they connected, and Nickelson and his wife, Teresa, flew to Spokane where they finally met in person. Johnson praised technology for helping them find one another and says there are more family members he plans to look for.

Spokane Valley Woman Finds Biological Father and 7 Half-Siblings After a DNA Test

When Spokane Valley resident Tracy Melton took a DNA test to learn more about her ethnic background, she never expected to find a biological father and seven half-siblings. Reynaldo Delgado, the man identified as her father, said he never knew she existed until she reached out to him and said, "I think you're my father." The two were even more shocked when they discovered that he and his family lived just 12 miles from her. The families have met in person and Melton and Delgado are forming a relationship. Melton says the whole thing still "feels very unreal."

Establishing Paternity in Spokane Valley

In the state of Washington, when a child is born to unmarried parents, steps must be taken to establish the child's legal paternity, also referred to as parentage. According to Spokane Valley fathers' rights attorneys at the Twyford Law Office, there are two ways to do this: voluntarily or through litigation.

The easiest method is for both parents to sign and file a Voluntary Acknowledgment of Parentage (AOP) form. However, this can only be done if both parents agree about the identity of the child's father and no one else has claimed to be the child's father.

If there is a dispute about the child's paternity, either parent can file a petition to establish paternity through the court system. Once paternity is legally established, parents can also request procedures to establish custody, visitation, and child support.
