A hemoglobin concentration of 112 g/L is normal for adult women and low for adult men. The normal range of hemoglobin for adult females is 110-150g/L and for adult males is 120-160g/L. When hemoglobin is between 90-120g/L, it is mild anemia, between 60-90g/L it is moderate anemia, between 30-60g/L it is severe anemia, and less than 30g/L it is very severe anemia. Therefore, when the hemoglobin result is 112g/L, it is normal for women, while for men it is mild anemia. It can be seen in diseases such as iron deficiency anemia and aplastic anemia. It is recommended that people with abnormal hemoglobin should clarify the cause of the disease under the guidance of a doctor and undergo standardized treatment.
