Antigens such as thermophilic actinomyces, fungi, and animal proteins have been identified as causative agents for hypersensitivity pneumonitis. Precipitating antibodies against the offending antigen can be demonstrated in most active cases of hypersensitivity pneumonitis. However, a positive test does not always indicate active disease since asymptomatic individuals may develop precipitins without any features of hypersensitivity. A positive test is a helpful diagnostic tool when supported by historical and clinical evidence. The absence of a positive test does not rule out hypersensitivity pneumonitis.
