Feather Mix (Chicken,Duck,Goose,Turkey) IgG

Test Code: 11220

Cpt Code:

86001 (x1)

Clinical Utility

Although there have been many publications concerning the measurement of allergen-specific IgG, the clinical utility of such tests has not been established except in special situations. Thus, the quantitative IgG test should only be ordered by specialists who recognize the limitations of the test. The normal reference ranges reported represent the expected results for individuals who have no unusual exposure and have not been immunized with the indicated allergen. The ranges reported have no disease-associated significance.

Procedure

Enzyme immunoassay (FEIA). A standard curve is used to calculate the specific IgG concentrations. The calibrators are referenced to the International Reference Preparation for serum immunoglobulins. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

Assay Range

The units are micrograms/mL of specific IgG. The reference varies by allergen.

  mcg/mL of IgG
Lower Limit of Quantitation* 2.0
Upper Limit of Quantitation** 200

Reference ranges vary by allergen.
