Methemoglobin

Category:

Methemoglobin

Description
Red Blood Cells (RBC) contain a protein called hemoglobin.   The function of hemoglobin is very important, since this protein adds oxigen when the RBC goes through the lumbs and after that it carries this oxigen to the entire body so body cells can work.  Afterwards it takes the CO2 that is a waste of the normal cellular function back to the lumps where it is expulsed by the respiration.
Methemoglobin is a type of hemoglobin that is unable to transport oxygen to tissues in blood. When the production of this protein is big enough leads to important health problems so this condition is called methemoglobinemia.
Its concentration is measured by means of analysis of a blood sample drawn from the vein in the arm.

• Acquired methemoglobinemia
