DNA Test – Richland, Washington

Richland WA DNA Testing Locations

Types of DNA Tests at our Richland, Washington 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 Richland DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

DNA Testing In The City Of Richland, Washington

Experts Say…

Pacific Northwest Family Law, located in Richland, WA, discussed DNA testing for proving paternity. The law firm explains that DNA testing is not necessary if both parents agree to sign the voluntary Affidavit of Paternity. However, some fathers may refuse to sign the affidavit or have doubts that they are the biological father. “…if you have any doubts about whether you are the father of a child, you should not sign the Affidavit. Instead, you should initiate a paternity case by filing a petition to establish paternity with your local county clerk’s office,” the firm stated, “you will have the chance to request genetic (DNA) testing through this process. Undergoing DNA testing is very common in paternity cases. DNA testing determines whether or not an individual is the father of a child with nearly 100% accuracy.”

Proving Paternity for Child Custody Purposes in Richland, WA

In Richland, WA, if two parents are unmarried, they have an opportunity to sign an Affidavit of Paternity. This form can be signed at the hospital when the child is born. This is the easiest way to establish paternity, but should only be signed if both parents have no doubts about who the biological father is. DNA testing to prove paternity is not required in Richland, WA to sign the voluntary affidavit. If either parent decides to rescind their signature, he or she must do so within 60 days of the form being filed.

Paternity may also be established through the court if two parents cannot agree to sign the Affidavit of Paternity. The court will likely order DNA testing to prove paternity. DNA samples will be taken from the mother, alleged father, and the child.

DNA testing may also be requested by either parent before establishing paternity. DNA testing analyzes whether the man is likely the child’s biological father.
