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

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. 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. 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.

Experts Say…

Pacific Northwest Family Law helps fathers in Kennewick and Benton County to establish paternity. “The term paternity refers to the legal relationship that exists between a father and child. Maternity, which is the legal relationship between a mother and child, is established immediately at the time of the child’s birth. But establishing paternity is not always this simple,” the law firm stated.

According to the firm, paternity may be established in three ways: presumption, acknowledgment, and parentage action. Reasons for establishing paternity include:

The child can have relationships with both parents.
The child can receive inheritance, property, or other rights.
The parents can share responsibility for the child.
The father can receive custody or visitation rights.

Proving Paternity for Child Custody Purposes in Kennewick, WA

When a child is born to parents that are married, the husband is the child’s legal father and paternity will not need to be established. But if the parents are not married, paternity will need to be established for the father to have parental rights to his child.

In Kennewick, WA, when both parents agree to sign an Acknowledgement of Paternity form, they do not need DNA testing to prove paternity. The form must be signed by the mother and the father, in front of a notary.

If a man denies paternity, paternity will need to be established through the court system. Either parent or the state of Washington can file a petition to establish parentage.

When there is the denial of paternity or either parent is unsure of who the biological father is, DNA testing will be ordered by the court. A DNA sample will be taken from the alleged father, mother, and child. DNA testing can show a 99.9 percent probability that a man is the father of the child.
