Question about food screening IgG

Question from Margret: Are the measurements of the IgG antibodies at the nutrition screening reliable also at
-continuous / frequent exposure?
-a depleted immune system?

A: In the case of overexposure, the test is certainly relevant.
In the case of a suppression, no, but then nothing responds in the study.
So as a confirmation that this is in play, I would definitely take the screening given that we then have to apply a re-education of the mucosa.
