was kostet ein großes blutbild beim arzt — what does this mean exactly?

A 'großes Blutbild' (complete blood count with differential) is a laboratory test that measures red blood cells, white blood cells, platelets, and the subtypes of white blood cells (neutrophils, lymphocytes, etc.). It is used to detect infections, inflammation, anemia, and blood disorders. Cost depends on indication: if medically necessary, German statutory health insurance covers it (approx. €10–20 in billing points). As a private self-pay service (IGeL), costs range from €20 to €50 depending on the lab and fee schedule (GOÄ). It is not a routine wellness test but a diagnostic tool. MyBody-X does not offer this test; their focus is on DNA and biomarker tests for prevention and lifestyle. For any health concerns, consult a physician.
