They can be useful if you are trying to prove that your injuries are the result of respiratory sensitivity to an allergen, ie diisocyanates, formaldehyde, etc. But the injury must be an IgM, IgE, etc. type of injury. I have seen them given by defense IME doctors after a pesticide exposure or a solvent exposure where chemically induced bronchitis or chemically induced RADS has occurred and the person has lost a significant amount of their respiratory function. The test is useless in this case since the victims did not have ALLERGIC reactions, but did have chemically injury to their lungs. A simple PFT would suffice. Methocholine challenge tests should only be given in a hospital. I personally witnessed one given in a doctors office in Los Angeles about 12 years ago. The railroad worker had severe lung damage from diesel exhaust fumes and had only about 35% normal FVC and FEV1 and the doctor was warned NOT to give him a methocholine challenge test. He did it anyway and EMTs took the guy to the hospital. The doctor was sued. DR. RICHARD L.
