High hemoglobin levels are a rare occurrence but is usually treated as a symptom for an underlying disease. Consulting a doctor is the best treatment, so they can diagnose your illness and give a recommended treatment plan to lower hemoglobin levels back to normal. [citation needed]
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]
One study found the median age at diagnosis to be 60 years, [9] while a Mayo Clinic study in Olmsted County, Minnesota found that the highest incidence was in people aged 70–79 years. [40] The overall incidence in the Minnesota population was 1.9 per 100,000 person-years, and the disease was more common in men than women. [ 40 ]
Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. [4] An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. [5] Both are potentially life-threatening disorders.
The model assumes that the hemodilute value is equal to the H m prior to surgery, therefore, the re-transfusion of blood obtained by hemodilution must begin when SBL begins. The RCM available for retransfusion after ANH (RCMm) can be calculated from the patient's H i and the final hematocrit after hemodilution(H m)
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
Methemoglobinemia, or methaemoglobinaemia, is a condition of elevated methemoglobin in the blood. [2] Symptoms may include headache, dizziness, shortness of breath, nausea, poor muscle coordination, and blue-colored skin (cyanosis). [2] Complications may include seizures and heart arrhythmias.

Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
