Hemoglobin is the main component of red blood cells and serves as the transporter for oxygen and carbon dioxide in the blood. Hemoglobin concentration (Hb) is usually reported as grams of hemoglobin per deciliter of blood (g/dL). Hb is commonly measured by the cyanhemoglobin (hemoglobin cyanide) method. A sample of blood is diluted in a solution of potassium ferricyanide and potassium cyanide, which oxidizes hemoglobin to hemiglobin (Hi; methemoglobin) and then converts it to hemoglobin cyanide (HiCN). The concentration of HiCN is then measured by spectrophotometry.
