Test Methodology

Qualitative Immunodiffusion.

Interpretation

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.

Analyte Specific Reagents (ASR) are used in many laboratory tests necessary for standard medical care and generally do not require U.S. Food and Drug Administration approval. This test was developed and its performance characteristics determined by ARUP Laboratories, Inc. It has not been approved by the U.S. Food and Drug Administration. This test should not be regarded as investigational or for research use.

Clinical Utility

This assay aids in the diagnosis of hypersensitivity pneumonitis.
