The FoodPrint Indicator test is designed to determine whether you have elevated food-specific IgG antibodies. If the indicator test returns a No response, it is unlikely that you have an IgG food sensitivity (intolerance). However if the result is Yes, then upgrading to a more detailed food test would be recommended. This is in order to determine to which specific foods you have raised IgG antibodies.
Fitzwilliam Food Test defines food sensitivity (intolerance) as a food- specific IgG antibody reaction.
The laboratory can run the full test from the blood sample already submitted for the Indicator Test (if ordered within six weeks of the blood collection).
