DNA Test – Gresham, Oregon

Gresham OR DNA Testing Locations

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

Establishing Paternity for Unmarried Couples in Gresham

According to the Oregon Department of Justice, there are several ways to establish paternity in Gresham and elsewhere in Oregon. First, if a mother is married at the time a child is born, her husband is automatically presumed to be the child’s father.

When a child is born to an unmarried mother, paternity can be established by:

Both parents signing a Voluntary Establishment of Paternity and filing it with the Oregon Department of Vital Records.
A mother filing a Declaration in Support of Establishing Paternity. This can be done with or without the alleged father’s permission.
Either the child’s mother or the alleged father can file a court action for legal establishment of paternity.

If the alleged father denies that he is the child’s parent, a DNA test will be needed to prove paternity before it’s legally established.

Importance of Establishing Paternity

Establishing paternity gives a child a stronger sense of identity and the emotional benefits that come with having both parents in their life. In addition, there are also legal and financial benefits for both the child and the parents. According to Ronald Johnston Family Law, which serves Portland, Gresham, and the surrounding area, some of the primary reasons to establish paternity include the ability to legally establish child support, child custody, and visitation. This also allows either parent to prevent or request the child’s relocation.

What Happens When Unmarried Parents Split?

When an unmarried couple has children, they’re both responsible for the child’s care and support. If they split up, it’s important to address the issues of child support and custody as soon as possible. The attorneys at Gresham-based Hedman Family Law state that once paternity is legally established, the courts will generally follow the same guidelines and laws applied to married couples. A father who wants to protect his rights should establish legal paternity as soon as possible.
