Introduction
Hematocrit (HCT) typically refers to the volume fraction of red blood cells (RBCs) in peripheral blood, expressed as a percentage of total blood volume. In adult males, the normal hematocrit range is generally 40%–50%; in adult females, it is typically 37%–48%; and in newborns, it usually ranges from 48% to 68%.
Both males and females have a value known as HCT (hematocrit), which refers to the volume percentage of red blood cells in whole blood. Prolonged selective eating in daily life—leading to inadequate nutrient intake—may cause anemia, resulting in reduced red blood cell volume. Consequently, HCT test results may fall outside the normal range. So, what constitutes a normal HCT value?
Normal HCT Values
HCT typically represents the proportion of red blood cells in peripheral blood relative to total blood volume, expressed as a percentage. In adult males, the normal hematocrit range is generally 40%–50%; in adult females, it is typically 37%–48%. In newborns, the normal hematocrit range is usually 48%–68%. An elevated hematocrit may result from intense emotional excitement or vigorous physical activity prior to testing; it may also indicate severe myocardial infarction.
A hematocrit value below the normal range may be caused by anemia or drug-induced effects, among other factors. If test results are abnormal, prompt medical evaluation at a hospital is recommended. If anemia is confirmed as the underlying cause, iron supplementation or other appropriate pharmacotherapy should be initiated under physician guidance.
During treatment, dietary intake of iron-rich foods—such as spinach and animal liver—is encouraged.
