Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
The levels of glycated hemoglobin are therefore measured in order to monitor the long-term control of the chronic disease of type 2 diabetes mellitus (T2DM). Poor control of T2DM results in high levels of glycated hemoglobin in the red blood cells. The normal reference range is approximately 4.0–5.9%.
A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:
Iron is an essential part of hemoglobin, and low iron levels result in decreased incorporation of hemoglobin into red blood cells. In the United States, 12% of all women of childbearing age have iron deficiency, compared with only 2% of adult men. The incidence is as high as 20% among African American and Mexican American women.

Iron is a mineral that is important in the formation of red blood cells in the body, particularly as a critical component of hemoglobin. [23] About 70% of the iron found in the body is bound to hemoglobin. [14] Iron is primarily absorbed in the small intestine, in particular the duodenum and jejunum.
Iron plays an essential role in many internal bodily functions, including producing hemoglobin — a protein in red blood cells that transports oxygen from the lungs to organs and tissues.
