Minimum standards for clinical laboratory test results and diagnostic X-ray results.

(1) Each nursing home, as a requirement for issuance or renewal of its license, shall require that all clinical laboratory tests performed for the nursing home be performed by a laboratory appropriately certified by the Centers for Medicare and Medicaid Services under the federal Clinical Laboratory Improvement Amendments and the federal rules adopted thereunder, except for such self-testing procedures as are approved by the agency by rule.

(2) Each nursing home, as a requirement for issuance or renewal of its license, shall establish minimum standards for acceptance of results of diagnostic X rays performed by or for the nursing home. Such minimum standards shall require licensure or registration of the source of ionizing radiation under the provisions of chapter 404. Diagnostic X-ray results which meet the minimum standards shall be accepted in lieu of routine examinations required upon admission and in lieu of diagnostic X rays which may be ordered by a physician for residents of the nursing home.
