Methemoglobin lab test
WebMethemoglobinemia is the critical health effect from exposure to nitrates and nitrites. Depending on the percentage of total MetHb, the clinical presentation may be one of oxygen deprivation with cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects [Skold et al. 2011]. WebThe potassium cyanide test can distinguish between methemoglobin and sulfhemoglobin. After the addition of a few drops of potassium cyanide, methemoglobin turns bright red, but sulfhemoglobin remains dark brown. This is due to the binding of methemoglobin to cyanide, forming cyanomethemoglobin, which is bright red in color.
