DNA Test - Rochester, New Hampshire

Rochester NH DNA Testing Locations

Types of DNA Tests at our Rochester, New Hampshire 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.

Rochester, NH - DNA Testing

Experts Say...

"There are many benefits to establishing paternity," said Russman Law, paternity lawyers serving Rochester and Strafford County. "It is important for a child to know their parents for both emotional and financial reasons. When the paternity of the father is identified, they can be held responsible for child support, insurance coverage, and other costs of raising the child. A person who is established as the father of a child also has the right to request custody or visitation with them."

Establishing Paternity in Rochester, NH

There are two ways unmarried parents can establish paternity in Rochester. If the parents agree on the child's biological father, they can sign a Paternity Affidavit, a voluntary form stating the child's legal father. The form must be notarized and filed with the New Hampshire Department of Health. Parents can find the Rochester location at 150 Wakefield Street, Suite 22.

If a parent denies or disputes paternity, they can begin a paternity action to establish paternity through the court, and the judge may require a DNA test to prove the child's biological father. A mother, an alleged father, the child's legal guardian, or the state of New Hampshire can open a paternity case.

Proving Paternity for Child Custody Purposes in Rochester, NH

If either parent denies or has doubts about the child's biological father, they should not sign a Paternity Affidavit until using DNA testing to prove paternity. Once the results determine that a man is the father, parents can choose to sign the voluntary form. If establishing paternity through a court order, the judge may order a DNA test. If the test does not exclude the man from being the child's father, the court takes steps to establish paternity. Once paternity is established, the father can add his name to the birth certificate and the parents can seek visitation, custody, and child support orders.
