Can Nährstoffcheck help with allergy?

A Nährstoffcheck (nutrient blood test) cannot diagnose allergies. Allergies are immune responses to specific allergens, detected via IgE antibodies or skin prick tests. A nutrient check measures levels of vitamins, minerals, and fatty acids that may influence immune function. For example, vitamin D or zinc deficiency might modulate allergic inflammation, but the evidence for a direct, clinically meaningful effect on allergy is weak and mostly mechanistic. The test is useful for identifying nutrient deficiencies, which could be part of a broader health strategy, but it is not a substitute for allergy testing. If you suspect an allergy, consult an allergist. Evidence: practice (for nutrient screening), mixed (for allergy relevance).
