(750 ILCS 46/402)

Sec. 402. Requirements for genetic testing.

(a) The genetic testing shall be conducted by an expert qualified as an examiner of blood or tissue types and appointed by the court. The expert shall determine the genetic testing procedures. However, any interested party, for good cause shown, in advance of the scheduled genetic testing, may request a hearing to object to the qualifications of the expert or the genetic testing procedures. The expert appointed by the court shall testify at the pre-test hearing at the expense of the party requesting the hearing, except for an indigent party as provided in Section 405 of this Act. An expert not appointed by the court shall testify at the pre-test hearing at the expense of the party retaining the expert. Inquiry into an expert's qualifications at the pre-test hearing shall not affect either party's right to have the expert qualified at trial.

(b) Genetic testing must be of a type reasonably relied upon by experts in the field of genetic testing and performed in a testing laboratory accredited by the American Association of Blood Banks or a successor to its functions.

(c) A specimen used in genetic testing may consist of one or more samples, or a combination of samples, of blood, buccal cells, bone, hair, or other body tissue or fluid.

(d) The testing laboratory shall determine the databases from which to select frequencies for use in calculation of the probability of paternity based on the ethnic or racial group of an individual or individuals. If there is disagreement as to the testing laboratory's choice, the following rules apply:

(1) The individual objecting may require the testing laboratory, within 30 days after receipt of the report of the genetic testing, to recalculate the probability of paternity using an ethnic or racial group different from that used by the laboratory.

(2) The individual objecting to the testing laboratory's initial choice shall:

(A) if the frequencies are not available to the testing laboratory for the ethnic or racial group requested, provide the requested frequencies compiled in a manner recognized by accrediting bodies; or

(B) engage another testing laboratory to perform the calculations.

(e) If, after recalculation using a different ethnic or racial group, genetic testing does not reputably identify a man as the father of a child, an individual who has been tested may be required to submit to additional genetic testing.
