About Genetic Testing

If Both the Mother and Possible Father Agree to Genetic Testing
Child Support Services will schedule the genetic tests. Both parties will be sent a letter indicating the time and place of the test. View a map of approved testing sites.

If Either Person is Not Willing to Take a Genetic Test
Child Support Services can order them to participate in testing. Genetic tests are scheduled and each person is notified of the time and place of the test. If the possible father does not show up, this is considered a “default” and Child Support Services then asks the court to name him as the father and order child support. Child Support Services may also ask the court to order him to pay for the genetic tests and legal fees.

After You Receive Genetic Testing Results
After you receive the genetic testing results and know who the father is, you and the other parent may establish legal fatherhood by signing an acknowledgment form from the Idaho Bureau of Vital Statistics or Child Support Services will ask a court to establish legal fatherhood and order child support.

About Genetic Testing
With the exception of identical twins, everyone has different DNA. Everyone receives half their DNA from their mother and half from their father. Genetic tests analyze a child’s DNA and determine which half came from the mother and whether the other half came from the possible father. 

Because of the unique nature of an individual’s DNA, genetic tests are extremely reliable. In most cases, genetic tests indicate with a “probability” of more than 99 percent certainty whether a man is a child’s father. If a man is NOT the father, genetic tests show this with 100 percent certainty.

Whenever possible, the mother, possible father, and child are tested to determine whether the man is the father. If the man is deceased or unavailable, his close relatives may be tested, since they share similar DNA.

Genetic tests are simple and painless. A cotton swab is brushed inside each cheek of your mouth, collecting DNA from your saliva. The samples are then sent to a laboratory for testing. Results are sent to Child Support Services and each parent within a few weeks.
