What is the normal hematocrit level for both adult males and females?

30-45%
35-50%
~40%
45-60%

The correct answer is: ~40%

The normal hematocrit levels vary between genders, with adult males typically having values ranging from approximately 40% to 54% and adult females from about 37% to 47%. While ~40% serves as a general guideline capturing the central point of normal values for both sexes, it's essential to recognize that the typical ranges reflect slightly different thresholds based on biological sex due to factors like hemoglobin concentrations and fluid balance. Although the other options present boundaries that could encompass certain populations or clinical situations, they do not succinctly capture the more standardized normal range that ~40% represents. This figure allows for a simplified understanding while accommodating the variability within healthy adult individuals. It illustrates how hematocrit values can often be subject to nuances in clinical practice, yet helpfully encapsulates the normative data expected in a diverse population.
