was kostet eine genanalyse — when to see a doctor?

The cost of a genetic analysis varies widely depending on scope and provider. Simple SNP tests (e.g., MTHFR, AQP3) often range from $50–$150, while comprehensive panels (e.g., skin DNA, microbiome) cost $150–$400. Importantly, these tests are typically lifestyle or wellness products, not medical diagnostics. You should see a doctor if you have specific symptoms (e.g., dry skin, sun sensitivity, unexplained fatigue) or a family history of certain conditions. The ACMG (American College of Medical Genetics) advises against routine MTHFR testing due to lack of clinical utility. For skin issues or sun damage, consult a dermatologist rather than relying on a DNA test. A vitamin D test should also be interpreted by a physician, as a single time-point may not reflect your true status. Bottom line: a genetic test can offer insights, but it cannot replace a medical evaluation. If you are unsure whether testing is appropriate, discuss it with your primary care provider first.
