IgG4 Food Panel VIII
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Corn IgG4 <0.15 mcg/mL
Egg White IgG4 <0.15 mcg/mL
Milk Cow IgG4 <0.15 mcg/mL
Peanut IgG4 <0.15 mcg/mL
Soybean IgG4 <0.15 mcg/mL
Wheat IgG4 <0.15 mcg/mL
The reference range listed on the report is the lower limit of quantitation for the assay. The clinical utility of food-specific IgG4 tests has not been established. These tests can be used in special clinical situations to select foods for evaluation by diet elimination and challenge in patients who have food-related complaints. It should be recognized that the presence of food-specific IgG4 alone cannot be taken as evidence of food allergy and only indicates immunologic sensitization by the food allergen in question. This test should only be ordered by physicians who recognize the limitations of the test.
