Additional Information
A normal Hct range for adults is typically between 40% and 54% for men and 37% and 48% for women. Abnormal Hct levels can indicate various health conditions, such as anemia, dehydration, or blood disorders. Hct is an essential component of a complete blood count (CBC) test, which is commonly used to diagnose and monitor various medical conditions.
Hct levels can be affected by several factors, including age, sex, altitude, and certain medical conditions. For example, people living at high altitudes may have higher Hct levels due to the lower oxygen levels in the air. Pregnant women may also experience changes in their Hct levels due to the increased blood volume during pregnancy.
Understanding Hct levels is crucial for healthcare professionals to diagnose and treat various medical conditions. Abnormal Hct levels can indicate underlying health issues, and prompt treatment can help prevent complications and improve patient outcomes.
Etymology
The term “hematocrit” comes from the Greek words “haima” (blood) and “kritikos” (separating). The term was first used in the late 19th century to describe the process of separating red blood cells from plasma.
