DNA Test - Portland, Oregon

Portland OR DNA Testing Locations

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

Portland, Oregano - DNA testing

Establishing paternity in Portland, OR

If the parents are not married when a baby is born, the easiest way to establish paternity in Oregon is to sign a Voluntary Acknowledgement of Paternity at the hospital. The hospital staff can provide the forms and witness the parent's signatures. In this case, no fee is charged, and the father's name will be added to the birth certificate. This form cannot be used if the mother is married to somebody else because the husband will be presumed as the legal father.

Either parent can also obtain a court judgment to establish parentage, and if one of the parties objects, the court is likely to require a DNA test before issuing the judgment. The judge may also consider other factors, such as the child's best interest.

The most accurate method of determining the birth father is with a DNA test. The court has the authority to order a DNA test for an alleged father, and if the test does show paternity with 99 percent certainty, it will be presumed.

Brother and sister meet after years thanks to a DNA test

In 1984, a little boy named Justin Kragt was found on the theater steps crying in South Korea. Less than a day later, a girl named Renee Alanko was dropped off at a market in the same area by her father. He told her she should buy some treats and he would pick her up later, but he never did. Justin was about two and a half years old, and Renee was four. Both of them found their adoptive parents in the United States.

Renee grew up in California, and Justin grew up in Oregon, but they had no idea they had a biological sibling so close by. In 2014, Kragt did a DNA test. He was hoping to find a cousin, but he had not even considered the possibility of finding a sister. Years later, when Alanko took a DNA test before having children, the results showed he had a sibling who also lived in the USA.

Kragt has heart problems, and he thought his parents gave him up because of that. He had no idea they gave up his sister, too, nor did he even remember he had a sister. Once they found out about each other, they started talking and finally met in Portland!
