wo kann ich allergietest machen — which blood markers matter?

Allergy testing is typically performed by allergists, immunologists, or specialized laboratories. Key blood markers include total immunoglobulin E (IgE), specific IgE against individual allergens (e.g., pollen, dust mites, foods), and sometimes eosinophil count. However, elevated IgE does not confirm allergy without clinical correlation. Direct-to-consumer DNA tests claiming to predict allergy risk lack robust evidence. The provided context does not include specific studies on allergy blood markers, so this answer relies on established medical practice. Always consult a healthcare provider before testing, especially for children or unclear symptoms. False positives and negatives occur; clinical history remains essential.
