was kostet großes blutbild — when to see a doctor?

A 'großes Blutbild' (complete blood count with differential) measures red and white blood cells, platelets, hemoglobin, hematocrit, and the distribution of white blood cell types. In Germany, it costs roughly €20–50 if paid privately (IGeL). Statutory health insurance covers it when medically indicated. When to see a doctor? Persistent fatigue, pallor, frequent infections, unexplained bruising or bleeding, fever of unknown origin, or suspicion of anemia, inflammation, or clotting disorders. Also before major surgery or in chronic disease monitoring. Important: A home test (e.g., fingerstick) cannot replace professional medical evaluation. Results must be interpreted by a physician in clinical context. Evidence: standard medical practice. Sources: none from the provided context.
