What is the normal hematocrit (Hct) range for adults?

The normal hematocrit (Hct) range for adults is indicated to be between 36% and 54%. Hematocrit is a measure of the proportion of blood that is made up of red blood cells and is expressed as a percentage. The normal range can vary slightly based on different population groups and laboratories, but typically, this range reflects enough of the typical variability in adult populations.

A hematocrit level within this range is crucial for ensuring adequate oxygen delivery to tissues and organs, which is essential for maintaining overall health. Values that fall outside of this range can indicate various health issues, including anemia if too low, or polycythemia if too high, which can impact blood viscosity and flow. Therefore, knowing the correct normal range is fundamental for nurses and healthcare providers when assessing a patient's hematological status.
