(750 ILCS 46/408)
    Sec. 408. Additional persons to be tested.
    (a) Subject to subsection (b), if a genetic-testing specimen is not available from a man who may be the father of a child, for good cause and under circumstances the court considers to be just, the court may order the following individuals to submit specimens for genetic testing:
        (1) the parents of the man;
        (2) brothers and sisters of the man;
        (3) other children of the man and their mothers; and
        (4) other relatives of the man necessary to complete
genetic testing.
    (b) Issuance of an order under this Section requires a finding that a need for genetic testing outweighs the legitimate interests of the individual sought to be tested, and in no event shall an order be issued until the individual is joined as a party and given notice as required under the Code of Civil Procedure.
