Hematocrit represents the proportion of blood volume comprised of red blood cells. A low measurement can indicate anemia, blood loss, or other underlying medical conditions. Conversely, increasing this proportion may be necessary in specific clinical scenarios, such as preparing for certain surgical procedures or addressing anemia related to specific causes.
Maintaining an adequate proportion of red blood cells is vital for sufficient oxygen delivery throughout the body. Tissues and organs require oxygen for proper function; a deficiency can lead to fatigue, weakness, and impaired cognitive function. Historically, methods to elevate red cell volume have been employed to enhance athletic performance or combat physiological challenges encountered at high altitudes.
