Haemoglobin is a protein present in red blood cells, responsible for transporting oxygen from the lungs to cells in the body. Haemoglobin gives red blood cells their distinctive colour. Haemoglobin levels differ between individuals, but men usually have higher haemoglobin levels than women.
A haemoglobin blood test measures the amount of haemoglobin present in your blood. The haemoglobin concentration gives a good insight into the blood’s ability to carry oxygen around the body.
Because haemoglobin carries oxygen from the lungs to cells around the body, low levels can signify anaemia where your body isn’t getting enough oxygen. Anaemia can cause symptoms like weakness and fatigue. Whereas, a high level can be a sign of polycythaemia where there are too many red blood cells in circulation.
You should make sure you are adequately hydrated when testing your haemoglobin levels. If you’re not, it can cause an abnormally high result.
