Seattle WA DNA Testing Locations

Types of DNA Tests at our Seattle, Washington locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

account_box
Grandparent DNA Test (if the father is not available for testing)
account_box
Sibling DNA Test (possible brothers, sisters, or half-siblings)
account_box
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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Seattle DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Seattle, Washington - DNA Testing

Establishing paternity in Seattle, WA

When a child is born to a married couple, the husband is automatically considered the father and there is usually no need to establish paternity.

If the couple is not married, there are two main ways of establishing paternity in Seattle. For the voluntary establishment of paternity, the parents can sign an Acknowledgement of Parentage. Alternatively, they can go to court if there is a dispute regarding paternity. People usually choose the court if they are unsure who the parent is, the parties do not agree about who the parent is, or they want to add or remove the parent from the child's birth certificate.

The court often orders a DNA test from a certified lab. An easy cheek swab test will be performed for the alleged father and the child to determine the relationship, and the lab's DNA experts will evaluate the DNA specimens. The timeframe for DNA test results can vary depending on the cooperation of each party and the clinic that was selected. The process can take longer if a party is uncooperative, and alternative specimens may be considered. Once the court has the DNA results, the judge establishes paternity.

Women who looked similar took a DNA test and discovered they were sisters

Shannon and Rachelle met for the first time because their friends had been telling them for years how similar they look and how they share many of the same mannerisms. Later, both women were teaching at the same school, and their colleagues also talked about how they could be sisters.


Shannon and Rachelle already had sisters but decided to take a DNA test anyway. They found out that all four of them were sisters and shared the same mother. The similarities between them are incredible. Not only do they look alike and display the same mannerisms, but they also both have bubbly personalities, sound the same, and share an interest in fashion. Shannon even said they were finishing each other's sentences. They could not be happier to take the test and finally learn about each other.
