Provides that if the alleged father is not excluded by the testing, the report shall contain statistics (instead of contain a combined paternity index relating to the probability of paternity) based upon a prescribed statistical formula. Provides that if the test shows that the alleged father is not excluded, any party may demand that other qualified experts perform tests using blood types or other tests of genetic markers (instead of genetic markers found by Human Leucocyte Antigen (HLA) tests). Provides that if the tests show that the alleged father is not excluded and that there is at least a 99.9 percent probability of paternity (instead of and that the combined paternity index is less than 500 to 1), the alleged father is presumed to be the father, and this evidence shall be admitted (instead of admitted and weighed with other competent evidence). Provides that a man identified as the father may rebut the DNA test results by other genetic testing that satisfies the Act which exclude the man as the father or identifies another man as the possible father (instead of any parentage presumption is rebutted if the court finds that the conclusion of an expert excludes paternity).

Provides that the test expenses shall be paid by the party requesting the tests, except that the court may apportion the costs between the parties, upon request (instead of paid by the party requesting the test)."
