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.

Facts about DNA Testing in Bellevue WA

The Discoverer of DNA Has Ties to Bellevue 

In 1953, scientist Francis Crick wrote a letter to his 12-year-old son Michael explaining that he had discovered “something beautiful” — the structure of DNA. The seven-page letter, which also included hand-drawn diagrams, was auctioned off in 2013 by Bellevue resident Michael Crick. The letter fetched a record-breaking $5.3 million, eclipsing the previous record of $3.4 million for a letter written by Abraham Lincoln.

A month after the letter was written, the research was published in the Journal Nature. Francis Crick, who died in 2004 at the age of 88, was awarded the Nobel Prize in medicine in 1962. Half of the proceeds from the sale of the letter were donated to the Salk Institute for Biological Studies in La Jolla, where the elder Crick was a professor.

Bellevue Attorney Weighs in on Paternity Issues

According to Bellevue attorney Jason S. Newcombe, paternity cases in the local area are almost always very emotionally charged. When paternity is questioned, Washington Family Court will require DNA testing to definitively establish paternity. While the results are straightforward, they also often set off a chain reaction that involves legal actions and requests for child support.

Bellevue attorneys handle many different types of paternity cases, including:

Any time a situation involves paternity issues, it’s usually a good idea to consult with an attorney. The stakes are high and the decisions that are made can last a lifetime.
