Hematocrit – what do your numbers mean?
Have you had your Hematocrit level measured and are unsure what the numbers mean? Here you will find a clear explanation of the normal range, what a too high or too low level can mean, and when it makes sense to get tested.
What is the normal range for Hematocrit?
What is the normal range for Hematocrit?
Hematocrit, also known as erythrocyte volume fraction (EVF), indicates the percentage of blood made up of red blood cells. The normal range for hematocrit varies depending on age, sex, and physiological conditions. For adult men, the normal range is typically between 0.40 and 0.50, while for women it is 0.35 to 0.46. Pregnant women have lower values, typically between 0.31 and 0.42. For children, the values vary with age, from 0.48-0.56 at birth to 0.28-0.42 for children between 8 weeks and 12 years. Laboratory differences may occur, and values close to the limits may indicate dehydration, anemia, or polycythemia, which is why further investigations may be necessary.
What does a low level mean?
A low hematocrit level can indicate anemia, where there is a reduced amount of red blood cells in the blood. Symptoms include fatigue, dizziness, shortness of breath, and paleness. Causes can include iron deficiency, chronic diseases such as kidney disease or inflammatory conditions, as well as blood loss from, for example, menstruation or gastrointestinal bleeding. Particularly vulnerable groups include women of childbearing age, the elderly, and people with chronic diseases. Treatment depends on the cause and may include iron supplements, treatment of underlying diseases, or blood transfusion in severe cases. It is important to seek medical advice for proper diagnosis and treatment.
What does a high level mean?
An elevated hematocrit level can be caused by polycythemia, where there is an increased amount of red blood cells, or dehydration, which reduces plasma volume. Symptoms may include headache, dizziness, redness of the skin, and high blood pressure. Causes can include chronic lung diseases, smoking, high altitude, or rarer conditions such as polycythemia vera. Treatment depends on the cause and may include fluid therapy, venesection, or treatment of underlying diseases. At values above 0.60, the risk of blood clots increases significantly, and it is important to seek medical advice for assessment and treatment.
