What is the normal hematocrit (Hct) range for adult females and males?

The normal hematocrit range for adult females and males is crucial in evaluating the body’s capacity to transport oxygen and can indicate various health conditions. For adult females, the typical hematocrit range is usually between 35% and 45%, while for adult males, it generally ranges from 38.8% to 50%. These values reflect the proportion of blood volume that is occupied by red blood cells, and understanding these ranges helps in identifying anemia, dehydration, and other hematological conditions.

The ranges provided in the other options diverge significantly from the medically accepted values. Specifically, the ranges in the second option are not expressed in percentage form, which is the standard measurement for hematocrit. Similarly, options that suggest excessively low hematocrit levels do not align with the physiological norms, as they fall well below the expected levels for both genders, indicating a misunderstanding of normal hematological values. The correct option aligns with established clinical guidelines and reflects a robust understanding of normal hematological health in both adult males and females.
