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]
However, co-oximetry can distinguish the methemoglobin concentration and percentage of hemoglobin. [3] At the same time, the SpO2 concentration as measured by pulse ox is false high, because methemoglobin absorbs the pulse ox light at the 2 wavelengths it uses to calculate the ratio of oxyhemoglobin and deoxyhemoglobin.
The pigment is a greenish derivative of hemoglobin which cannot be converted back to normal, functional hemoglobin. It causes cyanosis even at low blood levels. It is a rare blood condition in which the β-pyrrole ring of the hemoglobin molecule has the ability to bind irreversibly to any substance containing a sulfur atom.
Methylene blue is used to treat methemoglobinemia by chemically reducing the ferric iron in hemoglobin to ferrous iron. [6] [2] Methemoglobinemia can arise from ingestion of certain pharmaceuticals, toxins, or broad beans in those susceptible. [12]
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.

Beta-thalassemia (β-thalassemia) is an autosomal dominant blood condition that results in the reduction of hemoglobin production. The cause for the disorder is related to a genetic mutation of the HBB gene. This gene is responsible for providing the instructions to produce beta-globin; one of the major components of hemoglobin.
The hemoglobin was named hemoglobin III, [24] but hemoglobin C was eventually used. [ 25 ] [ 26 ] By 1954, it was found that the mutant hemoglobin was highly prevalent in West Africa. [ 27 ] [ 28 ] In 1960, Vernon Ingram and J. A. Hunt at the University of Cambridge discovered that the mutation was a single amino acid replacement of glutamic ...
A 2013 study of over 400,000 people admitted to US hospitals found that 74% developed anemia at some point during their hospital stay. [5] Iatrogenic anemia is of particular concern in intensive care medicine, [6]: 629 because people who are critically ill require frequent blood tests and have a higher risk of developing anemia due to lower hemoglobin levels and impaired production of red ...
