title: IgG4 FAST test in food allergic individuals: preliminary results.
abstract: We feel that one, the double blind oral food provocation protocol offers a reliable, realistic and objective method to make an observation and correlation of specific IgE and IgG4 antibodies to food allergy; second, these preliminary results thus far suggest a lack of "correlation" between history and skin tests, although there appears to be a better "correlation" between history and in vitro tests; third, these studies demonstrate a lack of "correlation" between skin tests and the presence of specific IgE and IgG4 antibodies to milk; and fourth, in spite of the positive symptom scores of the subjects, there was no direct relation between the numerical values of specific IgE and IgG4 milk antibodies to the oral milk provocation results.
