Clinical Significance
A diagnosis of Hypersensitivity Pneumonitis (an inflammatory lung disease) may be supported by detection of precipitating antibodies to a variety of inhaled antigens associated primarily with molds, bacteria and birds. A positive test does not always indicate active disease and a diagnosis should be supported by historical and clinical evidence, since healthy individuals occasionally might also develop precipitins. A negative test does not preclude a diagnosis of hypersensitivity pneumonitis and should be considered in the context of other laboratory results and clinical findings.
