What is the normal hematocrit range?

• A. 30-40%
• B. 40-50%
• C. 50-60%
• D. 20-30%

Answer: (B)

Hematocrit is the proportion of red blood cells in whole blood. For healthy adults, the normal range sits in the middle of the spectrum, commonly cited as about forty to fifty percent, with men typically slightly higher than women due to testosterone. A value below this range suggests anemia or blood loss, while a value above it suggests dehydration or polycythemia. Lab reference values can vary, but this mid-range is the standard NBRC reference used for interpretation.
