Bellevue WA DNA Testing Locations

Types of DNA Tests at our Bellevue WA clinics:

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

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

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 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 Bellevue DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Bellevue, Washington - DNA Testing

Proving Paternity for Child Custody Purposes in Bellevue, WA

Establishing paternity is necessary for unmarried Bellevue parents for the child to have a legal father. Paternity can be established voluntarily by signing an Acknowledgement of Parentage form. DNA testing is not required for parents to establish paternity but can be requested by either parent if paternity is in question. If the mother and the alleged father do not agree to establish paternity voluntarily, they can go to court, and the judge may order DNA testing to prove paternity.

Experts Say...

Molly B. Kenny, a divorce and child custody attorney in Bellevue, Washington, answers common questions about establishing paternity in Bellevue. "Paternity Acknowledgement is a legal document used to determine fatherhood. Both the father and the mother of the child will have to sign the form," says Kenny. Once the form is signed, notarized, and filed with the Washington State Department of Health, the child will have a legal father. Kenny explains that if there are questions about paternity or a paternity dispute, paternity can be established with a court order. "Either parent (the birth mother, presumed parent, or alleged parent) may file a Petition for Establishment of Parentage with the court," Kenny explains. "The petitioner then may serve the parent with the summons; the respondent may issue a response, and the case may proceed through the court system."

Importance of Establishing Paternity

For Bellevue fathers, establishing paternity allows them to have legal parental rights and responsibilities. Once a biological father becomes a child's legal father, he can obtain visitation and custody rights, travel with the child, and establish a relationship and connection with the child. Establishing paternity allows mothers to receive financial support. Children benefit from having two parents; they get a sense of belonging, access to medical information from both sides of the family, financial support, veteran's benefits, social security, and inheritance.
