Threshold levels of food allergens

Threshold level analysis revealed that 53 reactions occurred already to the lowest given allergen level of 0,1ml. Thus, for some patients there are threshold levels corresponding to a large drop of the food of animal origin already. There is virtually no safe amount of undiluted food that can be reproducibly given without reaction.

On the other hand, 50 patients reacted only after provocation of 144ml food. These patients may not be endangered by minute amounts and might even profit from contact to minute amounts because of tolerance induction. The reactivity to food allergens of animal origin is very individual.
