Clinical Indications

The clinical utility of food-specific IgG 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 IgG 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. The reference range listed on the report is the lower limit
of quantitation for the assay.
