What to watch with Pharmakogenetik Medicheck and Allergie?

When combining pharmacogenetic testing (e.g., Medicheck) with allergy tests, caution is warranted. Pharmacogenetic tests analyze genetic variants affecting drug metabolism (e.g., CYP450 enzymes). They can offer clues about drug tolerance or dosing, but they are not diagnostic and do not replace medical advice. Allergy tests (e.g., specific IgE) indicate sensitization, not necessarily clinical allergy. Combining both may lead to misinterpretation: a genetic 'risk variant' does not mean a drug will cause an allergic reaction, and a positive allergy test may have no pharmacogenetic relevance. Evidence for such combined consumer tests is weak – mostly marketing or mechanistic studies. Important: Do not self-medicate or change therapy without a doctor. These tests provide general guidance, not diagnoses. For suspected allergies or drug intolerances, clinical evaluation (e.g., provocation testing, physician-led pharmacogenetics) is essential.
