Depending on the levels of [[MetHb]] in the [[blood]] we can observe different symptoms as follows: MetHb of 15% presents with skin and blood color changes. Levels above 15% will result in [[hypoxia]] and levels above 70% can lead to death. 
*Methemoglobinemia must be differentiated from other diseases that cause [[hypoxia]] and [[cyanosis]], such as
 
There are several conditions that can present similar to [[methemoglobinemia]]. Note that the [[hypoxia]] in [[methemogobinemia]] will be unresponsive to [[oxygen]] treatment, in comparison to cardiac and pulmonary causes of [[hypoxia]]. Worth mentioning is also that high doses of [[antidote]] treatment for [[methemogobinemia]] ([[Methylene blue]]) can also cause [[cyanotic]] discoloration of the skin, but this does not mean that the treatment is inefficient. <ref>{{Rev Bras Anestesiol. 2008 Nov-Dec;58(6):651-64.
