Units and Reference Ranges / Interpretation
Units: mg/L
Range: <2.0 to >200
Comment: Values >7.9mg/L likely to indicate significant reaction to budgie antigens. Values >9.9mg/L likely to indicate significant reaction to bird antigens.

It has been shown that IgG antibody levels to pigeon serum > 10mgA/L are clinically significant and correlate well with significant exposure to both pigeon and other bird antigens.

In symptomatic patients such levels are highly likely to indicate Bird Fancier's Lung.

Similarly, it has been shown that serum IgG antibody levels to Budgie mix antigens >8mgA/L are likely to indicate sensitivity to that antigen source in symptomatic patients.
