Hemoglobin – what do your numbers mean?
Have you had your Hemoglobin level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a high or low level might indicate, and when it makes sense to get tested.
What is the normal range for Hemoglobin?
What is the normal range for Hemoglobin?
The normal range for hemoglobin varies depending on age, sex, and physiological conditions such as pregnancy. For adult men, the normal range is 8.3-10.5 mmol/L, while for women it is 7.3-9.5 mmol/L. For pregnant women, values typically range from 7.0-9.1 mmol/L, and for children, values depend on age but range from 5.5-14.9 mmol/L. Laboratories may have slight variations in reference intervals. Values close to the borderline can indicate incipient anemia or polycythemia, and it is important to assess this in conjunction with symptoms and other blood tests.
What does a low level mean?
A low hemoglobin level, also known as anemia, can lead to symptoms such as fatigue, dizziness, shortness of breath, paleness, and heart palpitations. The most common causes include iron deficiency, chronic diseases such as kidney failure or rheumatoid arthritis, and vitamin deficiencies such as B12 or folic acid. Particularly vulnerable groups are women of childbearing age, pregnant women, the elderly, and individuals with chronic diseases. If low hemoglobin is suspected, a doctor should be consulted for further investigations, which may include blood tests for iron, B12, and folate, as well as an assessment of any bleeding or underlying diseases.
What does a high level mean?
A high hemoglobin level can be caused by conditions such as polycythemia vera, chronic lung diseases, or dehydration. Symptoms can include headache, dizziness, redness of the skin, and high blood pressure. The condition can increase the risk of blood clots and often requires medical treatment. If symptoms occur or a high hemoglobin level is measured, a doctor should be consulted to determine the cause. Treatment may include fluid therapy for dehydration or more specific interventions for underlying diseases such as polycythemia vera.
