What is the normal adult Hb range for women?

• A. 12–15 g/dL
• B. 11–16 g/dL
• C. 13–17 g/dL
• D. 9–13 g/dL

Answer: (A)

Hemoglobin concentration shows how much oxygen-carrying protein is in the blood. In healthy adult women, the typical reference range is about 12 to 15 g/dL. This lower-to-mid range compared with men comes from physiological factors like menstruation and hormone differences that influence red blood cell production. Values around 12–15 g/dL are considered normal for nonpregnant adult women; lower values often indicate anemia, while higher values may point to dehydration, high altitude adaptation, or other conditions. Lab reference ranges can vary a bit by lab, but 12–15 g/dL is the standard range used for adult women in most nursing references, which is why this option is the best match.
