Introduction
Total hemoglobin is a protein responsible for oxygen transport. It is a red compound composed of iron and protein, and is one of the parameters measured in a complete blood count (CBC) to detect anemia. In addition, low hemoglobin levels may also be caused by leukemia, so a detailed medical examination at a hospital is necessary. Appropriate medications should be selected based on the specific underlying cause.
Total hemoglobin is a protein responsible for oxygen transport. It is an iron- and protein-containing red compound and one of the parameters measured in a complete blood count (CBC), primarily used to detect anemia.
Hemoglobin is the only iron-containing protein in the blood. The ferrous iron (Fe²⁺) within hemoglobin binds with oxygen, which is then delivered via the bloodstream to various organs throughout the body. Subsequently, hemoglobin carries carbon dioxide produced by tissues back to the lungs for exhalation. The normal range for hemoglobin is 110–160 g/L. When hemoglobin levels fall below this range, it indicates iron deficiency in the body, leading to anemia. This condition can be diagnosed by measuring total hemoglobin in a CBC test, or by evaluating two other indicators: mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). If either of these values is low, iron-deficiency anemia can be diagnosed. Treatment may include medications such as ferrous succinate tablets or ferrous gluconate tablets, taken under medical supervision.
In addition, low hemoglobin levels may also result from conditions such as leukemia. In such cases, a detailed medical evaluation at a hospital is necessary to determine the underlying cause, followed by appropriate drug therapy based on the specific diagnosis.
