was kostet ein gen test — what symptoms are typical?

The cost of a genetic test and the typical symptoms that lead to one cannot be generalized. Prices vary widely: single-gene tests (e.g., for lactose intolerance) often cost €50–150, while comprehensive DNA panels (metabolism, nutrition, health) range from €200 to €500. Common symptoms prompting a test include unexplained digestive issues (lactose, fructose, histamine intolerance), chronic fatigue, weight management problems, or a desire for personalized nutrition. Importantly, a genetic test alone is usually not diagnostic – it only indicates genetic predispositions. For actual symptoms, a doctor should always be consulted. The evidence for direct symptom–gene correlations is often moderate (human‑moderate) or based on GWAS. The provided context contains no specific information on costs or symptoms, so the evidence is rated as unclear.
