Conn. Gen. Stat. § 46b-500: Challenge to genetic testing results.

(a) Subject to a challenge under subsection (b) of this section, a person is identified under sections 46b-495 to 46b-505, inclusive, as a genetic parent of a child if genetic testing complies with said sections and the results of the testing disclose: (1) The person has not less than a ninety-nine per cent probability of parentage, using a prior probability of 0.50, as calculated by using the combined relationship index obtained in the testing; and (2) a combined relationship index of not less than one hundred to one.

(b) A person identified under subsection (a) of this section as a genetic parent of the child may challenge the genetic testing results only by other genetic testing satisfying the requirements of sections 46b-495 to 46b-505, inclusive, that:

(1) Excludes the person as a genetic parent of the child; or

(2) Identifies another person as a possible genetic parent of the child other than: (A) The person who gave birth to the child; or (B) the person identified under subsection (a) of this section.

(c) If more than one person other than the person who gave birth is identified by genetic testing as a possible genetic parent of the child, the court shall order each person to submit to further genetic testing to identify a genetic parent.
