For adult males is 130-170 g/L, and 120-150 g/L for adult females.
As haemoglobin is a chemical in a cell rather than a cell itself, it is measured by weight. The normal haemoglobin content of red blood cells is 115–150 grams per litre. This equates to approximately 27–34 picograms per red blood cell in one litre of blood. A picogram is one trillionth of a gram, or 1 x 10 -12 grams! The normal volume of red blood cells in one litre of blood is 77-98 femtolitres. A femtolitre is even smaller than a picolitre (1 x 10 -15 litres). Results from an FBC. Most FBCs come back with cell numbers in the normal range. About 5% of people that are tested will have a minor blood count abnormality. If there are symptoms associated with this abnormality, they can usually be treated quite easily. Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together. The iron contained in hemoglobin is also responsible for the red color of blood. Hemoglobin also plays an important role in maintaining the shape of the red blood cells. In their natural shape, red blood cells are round with narrow centers resembling a donut without a hole in the middle. The normal range for hemoglobin is: 1  For men, 13.5 to 17.5 grams per deciliter. 2  For women, 12.0 to 15.5 grams per deciliter. If your hemoglobin level is higher than normal, it may be the result of: 1  Polycythemia vera — a blood disorder in which your bone marrow makes too many red blood cells. 2  Lung disease. 3  Dehydration. 4  Living at a high altitude. Hemoglobin. Hemoglobin (/ˈhiːmɵˌɡloʊbɨn/); also spelled haemoglobin and abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates (with the exception of the fish family Channichthyidae) as well as the tissues of some invertebrates.  Well a study at Johns Hopkins University in Baltimore, which investigated 1000 women aged over 65, suggests otherwise. What they found was that within the normal range of haemoglobin, between 12 and say, 15, there was a remarkable difference in the levels of disability. Dr Paulo Chaves was one of the researchers. Paulo Chaves: The risk goes down as you increase from low normal levels, like 12, to 14.  Abnormally high numbers of red blood cells may indicate congenital heart disease, some lung diseases, dehydration, kidney disease or polycythaemia vera. 1  The normal red cell count for adult males is 4.5-5.5 x 1012/L, and 3.8-4.8 x 1012/L for adult females. Measuring the concentration of haemoglobin in the blood can help diagnose anaemia, a condition caused by a deficiency of haemoglobin. Anaemia can arise due to: 1  inadequate production of red blood cells in the bone marrow; 2  inadequate iron intake; This may occur in people with chronic lung disease, as an adaptation to high altitudes, or because of an abnormal increase in red cell production by the bone marrow (polycythaemia vera). 1  The normal haemoglobin level for adult males is 130-170 g/L, and 120-150 g/L for adult females. Measuring the concentration of haemoglobin in the blood can help diagnose anaemia, a condition caused by a deficiency of haemoglobin. Anaemia can arise due to: 1  inadequate production of red blood cells in the bone marrow; 2  inadequate iron intake; Reference ranges for blood tests are studied within the field of clinical chemistry (also known as clinical biochemistry, chemical pathology or pure blood chemistry), the area of pathology that is generally concerned with analysis of bodily fluids.  In the routine laboratory test for hemoglobin (Hb), it is usually measured as total hemoglobin and the result is expressed as the amount of hemoglobin in grams (gm) per deciliter (dl) of whole blood, a deciliter being 100 milliliters. Hemoglobin normal values: Hemoglobin is the oxygen-carrying pigment in the blood, the predominant protein in the red blood cells. A. The hemoglobin level is expressed as the amount of hemoglobin in grams (gm) per deciliter (dL) of whole blood, a deciliter being 100 milliliters. The normal ranges for hemoglobin depend on the age and, beginning in adolescence, the gender of the person. The normal ranges are: 1  Newborns: 17-22 gm/dL.
