hæmoglobinkoncentrationen

Hæmoglobinkoncentrationen, often abbreviated as Hb, refers to the amount of haemoglobin present in a specific volume of blood. Haemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the body's tissues and carbon dioxide from the tissues back to the lungs. The concentration of haemoglobin is a crucial indicator of the oxygen-carrying capacity of the blood.

Normal hæmoglobinkoncentrationen varies between individuals and is influenced by factors such as age, sex, and altitude. Generally, adult males have a slightly higher concentration than adult females. Values are typically expressed in grams per deciliter (g/dL) or millimoles per liter (mmol/L).

Low hæmoglobinkoncentrationen, known as anaemia, can result from various causes, including iron deficiency, vitamin B12 deficiency, chronic diseases, or excessive blood loss. Symptoms of anaemia may include fatigue, weakness, pale skin, and shortness of breath. Conversely, a high hæmoglobinkoncentrationen, termed polycythemia, can be caused by dehydration, certain genetic conditions, or prolonged exposure to high altitudes. This condition can increase the viscosity of the blood, potentially leading to blood clots.

Measuring hæmoglobinkoncentrationen is a standard part of a complete blood count (CBC) and is a vital diagnostic tool used by healthcare professionals to assess overall health and identify potential medical conditions.
