R.I. Gen. Laws § 15-8.1-604: Genetic testing results.

(a) An individual shall be identified as a genetic parent of a child if the genetic testing of the individual complies with this chapter and the results of testing disclose that the individual has at least a ninety-nine percent (99%) probability of parentage as determined by the testing laboratory.

(b) Identification of a genetic parent through genetic testing does not establish parentage absent adjudication under this chapter and a court may rely on nongenetic evidence to determine parentage, including parentage by acknowledgment pursuant to article 3 of this chapter or by admission pursuant to § 15-8.1-111, presumed parentage under article 4 of this chapter, de facto parentage under article 5 of this chapter, and parentage by intended parents under articles 7 or 8 of this chapter.

(c) An individual identified under subsection (a) of this section as a genetic parent of a child may rebut the genetic testing results only by other genetic testing satisfying the requirements of this chapter that:

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

(2) Identifies an individual, other than the individual who gave birth to the child, as a possible genetic parent of the child.
