Normal hemoglobin is usually 120 to 160 g/L for adult males, 110 to 150 g/L for adult females, and 170 to 200 g/L for newborns, respectively.
Hemoglobin levels vary among populations, with adult males having higher hemoglobin values than adult females, and newborns having the highest hemoglobin values.
People living in highland areas, due to the scarcity of oxygen, will be compensated to cause an increase in red blood cells, the hemoglobin content will also be physiologically higher, in order to bring more oxygen to the body.
The hemoglobin value is related to the environment, age group, pregnancy, gender, race, etc., and may show physiological changes. However, if there is a pathological increase or decrease, it is recommended to consult a doctor in time to clarify the cause of the disease and to carry out targeted treatment with the help of a doctor.
