What This Value Measures
Hemoglobin is the red blood pigment in erythrocytes that transports oxygen through the body. This value shows how well the blood can bind oxygen.
Elevated Value
An elevated level may indicate fluid deficiency, staying at high altitude, or increased production of red blood cells.
Low Value
A decreased level may indicate anemia, such as from iron deficiency, blood loss, or chronic diseases.
Note: Values differ between women and men; often slightly lower during pregnancy.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
