wie viel kostet ein allergietest — what can you do yourself?

The provided context does not include specific information on the cost or self-administration of allergy tests. Allergy tests (e.g., skin prick test, specific IgE blood test) are typically performed by a physician and cost between €50–200, often covered by insurance if medically indicated. Home self-tests (e.g., rapid IgE tests) are available but have limited accuracy: they measure total IgE or a few allergens, not the full spectrum. Self-diagnosis can be misleading because elevated IgE can also result from parasites or autoimmune conditions. The MyBody-X context documents do not mention any allergy test; they focus on DNA tests and biomarkers like ferritin. Therefore, evidence for self-administered allergy tests is weak. Recommendation: consult a doctor for proper diagnosis. Self-tests may serve as a supplementary orientation but not as a substitute for clinical evaluation.
