A district court may authorize the donation of a kidney of a ward with an intellectual disability to a father, mother, son, daughter, brother, or sister of the ward if:
(1) the guardian of the ward with an intellectual disability consents to the donation;
(2) the ward is 12 years of age or older;
(3) the ward assents to the kidney transplant;
(4) the ward has two kidneys;
(5) without the transplant the donee will soon die or suffer severe and progressive deterioration, and with the transplant the donee will probably benefit substantially;
(6) there are no medically preferable alternatives to a kidney transplant for the donee;
(7) the risks of the operation and the long-term risks to the ward are minimal;
(8) the ward will not likely suffer psychological harm; and
(9) the transplant will promote the ward's best interests.
