Evidence check: Pharmakogenetik Medicheck in the context of Allergie

The MyBody-X pharmacogenetics Medicheck in the context of allergies is marketed as 'inspirational hints' and not as a medical diagnosis. Evidence for pharmacogenetic testing in allergy medications (e.g., antihistamines, corticosteroids) is weak: no established clinical guidelines recommend routine genotyping before therapy. Most associations are based on small studies or mechanistic hypotheses, not on randomized controlled trials. Moreover, effect sizes of individual SNPs are small and overshadowed by lifestyle and environmental factors. Therefore, the test cannot reliably predict drug efficacy or side effects for allergy treatments. A doctor's consultation remains essential. The evidence rating is 'marketing/unclear' because the provided context lacks robust supporting data.
