High Hemoglobin Count



Hemoglobin or Hgb is an integral part of the Red Blood Cells or RBCs. Hgb is actually a protein that defines the oxygen-carrying capacity of blood and is hence, critical for our existence and the overall health of the human body. The most common test to detect high hemoglobin count is the Complete Blood Count test or the CBC test which is often conducted as a part of annual medical exams or routine testing procedures wherein bloodwork is involved. Since Hgb is found in RBCs, high RBC count usually means elevated levels of hemoglobin. However, this may not always be the case since the amount of Hgb carried by each RBC varies. Thus, there is a possibility that the RBC count may yield average results in the CBC test and the individual may still have a high hemoglobin count.



Understanding Hemoglobin Creation

To understand cases of elevated hemoglobin count, understanding hemoglobin formation in the human body is crucial. Each hemoglobin protein cell is composed of:

Heme—the heme part of the Hgb is formed through a complex procedure wherein multiple enzymes are involved. This is where the iron insertion into the Hgb cell happens and that is why, having low levels of iron is often linked to having Hemoglobin deficiency, though this isn’t always the case.

Globin—for every heme entity, two globin chains are formed to form one cell of hemoglobin. This is a standard formula for the formation of human hemoglobin and no variations are known unless there is a genetic disorder or some medical anomaly.

Understanding Normal Hemoglobin Levels

When testing for elevated hemoglobin levels, it is vital to know what is understood as common or acceptable Hgb level. The figures are expressed in gm/dl which is a worldwide measuring format wherein hemoglobin is expressed in the number of grams, per deciliter of whole blood. You should know that each deciliter equals 100 milliliter. The normal ranges of hemoglobin for various age-groups are:

Newborn babies: 17 to 22 gm/dl

Newborns, up to one-week old: 15 to 20 gm/dl

Toddlers up to one-month old: 11 to 15 gm/dl

Children and adolescents: 11 to 13 gm/dl

Adult men: 14 to 17 gm/dl

Adult women: 12 to 16 gm/dl

Men post middle-age: 12.3 to 14.8 gm/dl

Women post middle-age: 11.7 to 13.8 gm/dl
