was kostet ein blutbild — which blood markers matter?

The cost of a blood test depends heavily on the panel size and country. In Germany, statutory health insurance covers a small or complete blood count only with a medical indication (e.g., suspected infection, anemia). Without indication, you pay privately: roughly €20–50 for a small panel (CBC, inflammation markers), €50–150 for an extended profile (including liver, kidney, glucose, lipids). Which markers matter most depends on your health goal. For general prevention: HbA1c (long-term glucose), lipid panel (LDL, HDL, triglycerides), vitamin D, ferritin (iron status), hs‑CRP (inflammation). For longevity: HbA1c, vitamin D, liver enzymes (GGT, ALT), kidney function (creatinine, eGFR). Evidence is mostly human‑moderate to mechanistic – many markers are surrogate endpoints, not direct longevity guarantees. Caution: consumer tests often overpromise; a blood test is a snapshot, not a genetic prediction. Always consult a physician before interpreting results yourself.
