What is the normal reference range for adult female hematocrit (Hct)?

• A. 36.1–44.3%
• B. 34.0–42.0%
• C. 38.0–46.0%
• D. 32.0–40.0%

Answer: (A)

Hematocrit shows the percentage of red blood cells in the blood, and for adult females the normal range is generally in the mid-30s to mid-40s percent. In many labs this sits around 36% to 44%, reflecting typical red cell mass in nonpregnant adult women. The option 36.1–44.3% matches this commonly used range most closely, making it the best choice. Other ranges either sit too low, too high, or skew toward values more typical of males or specific conditions, so they don’t fit the standard reference interval as well.
