wie viel kostet großes blutbild — can a DNA test help?

A comprehensive blood count (großes Blutbild) in Germany costs roughly 30–100 € as a self-pay test, depending on the lab and scope. If medically indicated, statutory health insurance covers it. A DNA test cannot replace a blood count. DNA tests provide information on genetic predispositions (e.g., for nutrient deficiencies or metabolic variants) but not current levels of hemoglobin, white blood cells, or inflammatory markers. The evidence for DNA tests in routine health questions is weak to moderate – many results come from GWAS with limited clinical predictive power. A blood count, by contrast, is a well-established, evidence-strong diagnostic tool. DNA tests may offer complementary hints, e.g., in unexplained deficiency states, but never substitute a doctor-ordered blood test. Beware of marketing claims: no DNA test can diagnose a medical condition.
