Genetic tests

Genetic (DNA) tests can be done either by a "buccal swab" test or by a blood test. Most places do the swab test instead of a blood test. For the swab test, cotton swabs are rubbed inside the mouth to obtain cell samples. In both types of testing, samples are taken from the man, the mother and the child. The results from these tests will determine the probability of a specific man being the father.

The court uses the test results to rule on paternity when the man or mother are not sure or do not agree on the paternity of the child. If the tests show a 99% or greater probability of paternity, the man will be presumed to be the father under Wisconsin law. The man has the right to object to the test results in court.

If you are not sure if a man is the father, you should ask for genetic testing.

Who pays for the genetic tests?

The child support agency pays for the tests until paternity is established. If the tests show that a man is the father, he and/or the mother may be ordered to pay for the tests. If the tests show that a man is not the father, he will not be charged for the tests.

Child support agencies offer genetic testing at a reduced price.
