What is the normal range for human hemoglobin?

Hemoglobin transports oxygen and is primarily found in red blood cells, supplying oxygen to all organs and tissues of the body. The normal hemoglobin level for adult males is ≥120 g/L. A level below this threshold suggests anemia, which may lead to chronic tissue hypoxia and ischemia. It is recommended that you consult a hematologist at a hospital for evaluation and guidance on appropriate pharmacological treatment to correct the anemia. Regular follow-up testing is advised, and dietary improvements—including increased nutritional intake—are also beneficial.
