Description

Clinical Utility: Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis is a diffuse inflammation of the peripheral airways of the lung. It is caused by repeated inhalation of a variety of organic dust allergens including animal and vegetable products, fungi and bacteria. Frequently the etiologic agents are associated with the patient's occupational environment. Tests included in this panel: Alternaria tenuis/alternata IgG, Aspergillus fumigatus IgG, Aureobasidium pullulans IgG, Laceyella sacchari IgG, Micropolyspora faeni IgG, Penicillium Chrysogenum/notatum IgG, Phoma betae IgG, Trichoderma viride IgG. Thermoactinomyces vulgaris IgG is no longer included in this panel as of 06/06/2022.

Reference Values:

Alternaria tenuis/alternata IgG: <12.0 mcg/mL
Aspergillus fumigatus IgG: <46.0 mcg/mL
Aureobasidium pullulans IgG: <18.0 mcg/mL
Laceyella sacchari IgG: <25.0 mcg/mL
Micropolyspora faeni IgG: <5.0 mcg/mL
Penicillium Chrysogenum/notatum IgG <22.0 mcg/mL
Phoma betae IgG: <8.0 mcg/mL
Trichoderma viride IgG: <10.0 mcg/mL

Antibody levels greater than the reference range indicate that the patient has been immunologically sensitized to the antigen. The significance of elevated IgG depends on the nature of the antigen and the patient's clinical history.
