Illinois Code § 404

§ 404.

Effect of genetic testing. Genetic testing taken under this Article shall have the following effect: (a) If the court finds that the conclusion of the expert or experts, as disclosed by the evidence based upon the genetic testing, is that the alleged father is not the parent of the child, the question of paternity shall be resolved accordingly. (b) If the experts disagree in their findings or conclusions, the question shall be weighed with other competent evidence of paternity. (c) If the genetic testing results indicate that the alleged father is not excluded and that the combined paternity index is at least 1,000 to 1, and there is at least a 99.9% probability of paternity, the alleged father is presumed to be the father, and this evidence shall be admitted. (d) A man identified under subsection (c) of this Section as the father of the child may rebut the genetic testing results by other genetic testing satisfying the requirements of this Article which: (1) excludes the man as a genetic father of the child; or (2) identifies another man as the possible father of the child. (e) Except as otherwise provided in this Article, if more than one man is identified by genetic testing as the possible father of the child, the court shall order them to submit to further genetic testing to identify the genetic father.
