was kostet ein großes blutbild beim arzt — what symptoms are typical?

The provided contexts contain no information about the cost of a complete blood count (CBC) at a doctor's office or the typical symptoms that warrant such a test. A CBC is commonly ordered for symptoms like fatigue, weakness, pale skin, shortness of breath, frequent infections, or unexplained bruising/bleeding. Costs vary by country, insurance, and practice; in Germany, statutory health insurance usually covers it if medically indicated. Without indication, out-of-pocket costs may range from €20–50. Since the contexts lack relevant data, this answer is based on general medical knowledge, not the provided sources. Evidence is rated as 'practice' but without direct support from the given texts.
