Hemoglobin (Hb)

Not another damn test

OK Daddy What is Hemoglobin? Hemoglobin (abbreviated Hb) is a red substance made of iron and protein Carries Oxygen to the cells Carries Carbon dioxide away from the cells

Each molecule of hemoglobin contains four groups of heme. Heme is the iron component of hemoglobin. Each group of heme can carry one molecule of oxygen.

A Hemoglobin molecule contains four globin polypeptide chains composed of amino acids. Amino acids are a group of chemical substances that form proteins. Each hemoglobin molecule consists of about 3.8% heme and 96.2% globin.

Normal Levels 12 to 16 grams per deciliter (g/dl) in women 13.5 to 18 in men

High Levels Congenital Heart Disease Excessive Eythropoietin (hormone) Polycythemia vera Pulmonary Fibrosis

Low Levels Lead Poisoning Bleeding Poor nutrition Overhydration Too Little Erythropoietin (from kidney disease) anemia

Stat Hb and Trauma Recent studies show early downward shifts in Hb levels are indicative of severe trauma.

Women and MI Another study shows low Hb levels are often associated with increased mortality in MI in women.

Field Hb Testing The field test unit works like a glucometer. This is a CLIA waved test.
