Hæmoglobinniveau

Hæmoglobinniveau refers to the concentration of hemoglobin in a person's blood. Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs to be exhaled. Measuring hæmoglobinniveau is a common diagnostic test used to assess overall health and detect various medical conditions.

Normal hæmoglobinniveau varies slightly depending on age, sex, and physiological state. Generally, adult men have a slightly higher range than adult women. Pregnant women typically have lower levels due to increased blood volume. Infants and children have different reference ranges that change as they grow.

Low hæmoglobinniveau, known as anemia, can be caused by several factors. These include iron deficiency, vitamin B12 deficiency, folate deficiency, chronic diseases, blood loss, and certain genetic disorders affecting red blood cell production or lifespan. Symptoms of anemia can include fatigue, weakness, pale skin, shortness of breath, and dizziness.

High hæmoglobinniveau, known as polycythemia, can be a response to chronic low oxygen levels, such as in people living at high altitudes or those with certain lung diseases. It can also be caused by bone marrow disorders or dehydration. Symptoms may include headache, dizziness, itching, and redness of the skin.

Hæmoglobinniveau is typically measured using a complete blood count (CBC) test, which is part of routine medical check-ups. Maintaining an appropriate hæmoglobinniveau is crucial for ensuring adequate oxygen supply to all parts of the body.
