was ist ein guter hb wert — what are common causes?

A good hemoglobin (Hb) value depends on age, sex, and individual factors. For adult men, 13.5–17.5 g/dL is normal; for women, 12.0–15.5 g/dL. Children and pregnant women have different reference ranges. Low Hb (anemia) commonly results from iron deficiency, vitamin B12 or folate deficiency, chronic inflammation, blood loss, kidney disease, or bone marrow disorders. High Hb can be due to dehydration, smoking, chronic lung disease, or polycythemia vera. Further lab tests (ferritin, transferrin, B12, reticulocytes) and medical evaluation are needed to identify the cause. MyBody-X does not directly measure Hb; the values cited are from established medical guidelines. Note: home Hb tests are often inaccurate; clinical diagnosis is essential for abnormalities.
