We didn’t realize just how ill my mother was. As my mother walked into the emergency department, her shockingly low hemoglobin (Hb) level was 3.5 g/dL. Normal hemoglobin levels for a woman range from 12.0 to 16.0 g/dL. The nurse confided that she had never seen such low hemoglobin in a person who was conscious much less alert and ambulatory (however weak). The doctor said that such a low Hb level could cause a heart attack.
Hemoglobin is the protein molecule in red blood cells...
