Hemoglobin Levels (cont.)
IN THIS ARTICLE
How is hemoglobin measured?
Hemoglobin is routinely measured as part of a routine blood test termed blood count (CBC). A complete blood count is one of the most common tests doctors order for a patient. It is done on automated machines that use a blood sample that is chemically treated to release hemoglobin from red blood cells. The released hemoglobin then is bound chemically to cyanide that forms a compound that absorbs light. The amount of absorbed light is then measured, and this measurement is directly related to how much hemoglobin is present in the blood.
