What is the normal reference range for hemoglobin in adult females?

• A. 10-14 g/dL
• B. 11-15 g/dL
• C. 12-16 g/dL
• D. 9-13 g/dL

Answer: (C)

Normal reference range for hemoglobin in adult females is about 12-16 g/dL. Hemoglobin is the oxygen-carrying protein in red blood cells, and female values tend to be a bit lower than males due to factors like menstruation and hormonal differences. A level below 12 g/dL suggests anemia, while a level above 16 g/dL is not typical for healthy adults and can indicate dehydration, high altitude effects, or polycythemia. While some labs may use slightly different cutoffs, 12-16 g/dL is a commonly cited range for adult females.
