Interpretive

Reference Range:

≥16 years: ≤53.3 mg/L

Elevated concentrations of IgG antibodies to pigeon droppings are consistent with the diagnosis of HP caused by exposure to this antigen. Negative results do not rule out the disease.

Critical Values:

N/A

Limitations:

IgG antibodies to pigeon droppings are detectable in healthy individuals, and the presence of antibodies is not sufficient to establish the diagnosis of HP caused by exposure to this antigen.

The levels of antibodies decrease following successful treatment of HP; but, elevated levels may persist for long periods.

The measurement of IgG antibodies to pigeon droppings should not be relied upon exclusively to establish the diagnosis of HP.

Methodology:

Fluorescence Enzyme Immunoassay (FEIA)

Contraindications:

N/A
