How is hypersensitivity pneumonitis diagnosed?
Many people with episodes of hypersensitivity pneumonitis are probably unrecognized and undiagnosed. Some cases believed to be viral pneumonias may actually be hypersensitivity pneumonitis. The patient’s history of repeated episodes of typical symptoms, hours after exposure to certain environments are important in establishing the diagnosis. Blood antibody tests and skin tests against certain offending molds, bacteria, or particles are also available but their results are usually inconclusive. The interpretation of these tests is complicated, and is best performed by a doctor experienced in hypersensitivity pneumonitis. The most accurate determination of the cause of hypersensitivity pneumonitis is a detailed exposure history. What is the treatment of hypersensitivity pneumonitis? The most important treatment of hypersensitivity pneumonitis is avoidance of repeated exposures to the offending particles. With early diagnosis and prevention, the prognosis is good.
