21. “Pulmonary function test” means spirometry, lung volume testing, and diffusion capacity testing, including appropriate measurements, quality control data, and graphs, performed in accordance with the methods of calibration and techniques provided in the applicable AMA guides and all standards provided in the official statements of the American thoracic society in effect on the day pulmonary function testing of the exposed person was conducted.
22. “Qualified physician” means a physician who is board-certified in internal medicine, board-certified in pathology, board-certified in pulmonary medicine, or board-certified in occupational medicine, as may be appropriate to the actual diagnostic specialty in question, and for whom all of the following are true:
a. The physician conducted a physical examination of the exposed person and has taken a detailed occupational, exposure, medical, smoking, and social history from the exposed person, or if the exposed person is deceased, has reviewed the pathology material and has taken a detailed history from the person most knowledgeable about the information forming the basis of the asbestos action or silica action.
