PEG IgG
REFERENCE RANGE: < 3.5 mg/dL
INTERPRETIVE CRITERIA:
< 3.5 mg/dL Normal level
> or = 3.5 mg/dL Elevated level
The PEG method is both antigen and antibody non-specific and is based on the property of immune complexes to precipitate at low concentrations of PEG (2.5-3.5%). The PEG method will precipitate immune complexes of various sizes and composition as well as other macromolecules present in serum. Elevated serum IgG may cause a false positive increase in the PEG precipitate.
