Types of DNA Tests at our Kennewick, Washington clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

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 alleged father and child or children. 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 ordering one of our testing kits online and shipping the specimens back to us.

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. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Kennewick DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Importance of Establishing Paternity in Kennewick, WA

If a Kennewick mother is unmarried at the time of her child's birth, only she will possess parental rights until both she and the child's biological father establish paternity. Establishing paternity in the state of Washington is crucial, as it declares the legal father and preserves his paternal rights. Established paternity will be necessary to request child support services, custody, or visitation.

More importantly, establishing paternity in the state of Washington also preserves the well-being of the child. With two legal guardians, a child is entitled to a multitude of benefits from both parental parties, including social security benefits, military benefits, and health insurance coverage.

Using DNA Testing to Help Establish Paternity in Kennewick, WA

To establish paternity in Washington, both parents can complete an Acknowledgment of Parentage form at the hospital following a child's birth or through a Benton County Child Support Services Office. Because this is a legally binding process, both parents should first consider the use of DNA testing services to accurately identify the biological father before moving forward with the form.

If a parent must seek the assistance of the courts to establish paternity, a judge will also often request that the presumed father first undergo DNA paternity testing before the court establishes paternity. Verifying the genetic father of a child before establishing paternity helps eliminate the concern of future legal complications if mistaken paternity is learned at a later date.

Experts in Kennewick, WA Say…

After two Kennewick parents have established paternity, they may move forward with establishing a custody plan in court. According to Kennewick family law attorney Kari Hayles-Davenport, the court uses Washington Revised Code Section 26.09.187 to determine the criteria that dictate a custody plan. Factors considered when developing a plan include the child's wishes, the financial needs of the child, and whether one or both parents are granted decision-making authority.
