Question: what hgb level is anemia?
Answer: Hemoglobin, or Hb, is usually expressed in grams per deciliter (g/dL) of blood. A low level of hemoglobin in the blood relates directly to a low level of oxygen. In the United States, anemia is diagnosed if a blood test finds less than 13.5 g/dL in a man or less than 12 g/dL in a woman.
