WebCarbaminohemoglobin (carbaminohaemoglobin BrE) (CO 2 Hb, also known as carbhemoglobin and carbohemoglobin) is a compound of hemoglobin and carbon dioxide, and is one of the forms in which carbon dioxide exists in the blood.Twenty-three percent of carbon dioxide is carried in blood this way (70% is converted into bicarbonate by … WebHemoglobin levels are typically evaluated through the complete blood count (CBC) test. CBC is a routine test your healthcare provider may order to help diagnose various conditions, including infections, anemia, and leukemia. A hemoglobin count that's either too low or too high can adversely affect your health.
