What is the normal range for hemoglobin (Hb) levels?

• A. 10-12 g/100 mL blood
• B. 12-16 g/100 mL blood
• C. 14-18 g/100 mL blood
• D. 16-20 g/100 mL blood

Answer: (B)

The normal range for hemoglobin (Hb) levels typically falls between 12-16 g/100 mL of blood for women and 14-18 g/100 mL of blood for men, making the range of 12-16 g/100 mL a suitable answer as it accurately reflects the lower end of normal values for adult women. Hemoglobin is a critical component of red blood cells and is essential for transporting oxygen throughout the body. Levels below this range may indicate anemia, while significantly higher levels could suggest polycythemia. Thus, recognizing this normal range is vital for evaluating a patient's hematologic status and ensuring proper diagnosis and treatment.
