Is it normal to have a high hemoglobin count?

It is often a misconception to consider high hemoglobin levels as adequate. High hemoglobin has no co-relation with the levels of iron and red blood cells in blood. Very often, patients with high hemoglobin levels have normal red blood cell count. Any hemoglobin reading above the upper limit of the normal range mentioned is considered to be high.

What should be included in a workup of an elevated hemoglobin?

Normal results on arterial blood gas studies (carbon monoxide, oxygen saturation) indicate a need for a study of the oxygen affinity of hemoglobin (P 50 study). This test is available in many laboratories.

What should my hemoglobin level be before surgery?

The journal Critical Care reports that critically low levels of hemoglobin are generally classed as anything below 8 g/dL or 8.5 g/dL. When hemoglobin levels fall so low, doctors may have to put off surgery and raise hemoglobin levels.

Your age and gender both affect your Hgb levels. Typical healthy Hgb levels are as follows: For men, Hgb levels below 13 g/dL are considered low. For women, Hgb levels below 12 g/dL are considered low if not pregnant. This threshold may change with certain conditions.

What should the blood count be for high hemoglobin?

Different doctors apply slightly different definitions for “high” hemoglobin (abbreviated Hb or Hgb). In the United States, most doctors would define high hemoglobin counts as anything over 17.5 grams (g) of hemoglobin per deciliter (dl) of blood for men, or 15.5 g/dl for women who are still menstruating.

The hemoglobin (Hgb) test measures how much hemoglobin your red blood cells contain. Hgb is a protein produced by your bone marrow that’s stored in red blood cells.
