(750 ILCS 46/404)
    Sec. 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 genetic parent is not the parent of the child, the question of parentage shall be resolved accordingly.
        (b) If the experts disagree in their findings or
    
conclusions, the question shall be weighed with other competent evidence of parentage.
        (c) If the genetic testing results indicate that the
    
alleged genetic parent is not excluded and that the combined parentage index is at least 1,000 to 1, and there is at least a 99.9% probability of parentage, the alleged genetic parent is presumed to be the parent, and this evidence shall be admitted.
        (d) A person identified under subsection (c) of this
    
Section as the parent of the child may rebut the genetic testing results by other genetic testing satisfying the requirements of this Article which:
            (1) excludes the person as a genetic parent of
        
the child; or
            (2) identifies another person as the possible
        
parent of the child.
        (e) Except as otherwise provided in this Article, if
    
more than one person is identified by genetic testing as the possible parent of the child, the court shall order them to submit to further genetic testing to identify the genetic parent.
