What should I know about allergiewert blut?

The term 'allergy blood value' typically refers to measuring specific immunoglobulin E (IgE) in the blood, the gold standard for diagnosing type I allergies. Elevated IgE can indicate sensitization to allergens (pollen, food, animal dander), but clinical symptoms and provocation tests are required for confirmation. MyBody-X does not offer validated genetic allergy diagnostics. Genes like IL1B or VDR mentioned in the knowledge base relate to inflammation or vitamin metabolism, not allergy specifically. Commercial DNA tests claiming to predict 'genetic allergy risk' rely on weak associations (e.g., small-effect GWAS loci) and are not clinically established. The evidence for such tests is best rated as 'marketing'. In contrast, a standard IgE blood test ordered by a physician is evidence-based (practice). Caution: normal IgE does not rule out allergies, and elevated IgE can also occur with parasites or autoimmune conditions. Always consult a doctor before making dietary or medication changes based on genetic test results.
