was sagt ein großes blutbild aus — when to see a doctor?

A complete blood count (CBC) provides information about red and white blood cells, hemoglobin, hematocrit, and platelets. It helps detect anemia, infections, inflammation, or bleeding disorders. You should see a doctor if you experience symptoms like fatigue, pale skin, shortness of breath, unexplained bruising, or fever. It is also useful as a routine check-up. The provided context focuses on DNA tests, not blood tests, so I cannot directly reference it. The evidence for CBC utility is strong in clinical practice, but interpretation requires a physician.
