was kostet großes blutbild — can a DNA test help?

A complete blood count (CBC) measures current levels of red/white blood cells, hemoglobin, and platelets. A DNA test cannot replace this because it only shows genetic predispositions, not actual blood values. Some companies (e.g., MyBody-X) market gene variants (APOA2, TCF7L2) related to metabolism or cholesterol, but effect sizes are small and not diagnostic. In Germany, a CBC costs roughly €5–€50 depending on insurance status and lab. A DNA test typically costs €100–€300 and provides no acute blood results. Both tests can be complementary but are not interchangeable. Evidence for actionable diet changes from consumer DNA tests is weak to moderate. Always consult a doctor before making health decisions based on genetic results.
