DNA Test – Grants Pass, Oregon

Grants Pass OR DNA Testing Locations

Types of DNA Tests at our Grants Pass, Oregon 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:

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 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 Grants Pass DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Grants Pass Woman Finds Sister After 70 Years

Joyce Lewis Wyatt bounced from one foster home to the next after being separated from her family at a very young age. Eventually, she landed in Grants Pass. After 70 years, she had given up on ever finding her biological family.

In the meantime, Margie Lewis Weber, who lived across the country, never stopped searching for the sister she knew she had. Any time she met or heard of someone named Joyce, she would grill them with questions, hoping to learn that the person was, in fact, her long-lost sister.

Everything changed when each of the women’s sons suggested a DNA test. It took some effort and quite a bit of research, but the two finally connected, despite living 2,500 miles apart. They first reached out by phone and then meet in person a week later. Both say they feel like their prayers have been answered. They’re now looking for a third sister they’re still hoping to connect with.

Establishing Paternity in Grants Pass

In Grants Pass, and other cities in Oregon, there are multiple ways for unmarried parents to establish paternity. When the father and mother agree, the easiest method is for both to sign a voluntary acknowledgment of paternity. The form must be notarized and filed with the Oregon Vital Records department.

A child’s mother can also file an “Affidavit in Support of Establishing Paternity,” either with or without the alleged father’s signature. If the alleged father does not agree, he can take a DNA test to determine paternity. A man can go through a similar process if he believes he has fathered a child and wishes to establish paternity.

Once paternity has been legally established, the courts can also rule on important topics like child support, custody, and visitation rights.
