Question: Methemoglobin in anemic patients

 Silviu - Tue Oct 20, 2009 11:09 am


I read that normal values of methemoglobin are below 1% for healthy individuals. What happens in anemic patients, is it still 1% or or do you typically observe higher values?

Thanks, Silviu.

User avatar Hello,Unless a person has a hereditary gene the available hemoglobin remains saturated even in anaemia thanks to enzymes that prevent methHB formation ie NADH enzymes keeping the levels to normal.So in co-oxymetry tests it will be less than 1 percent.Unless of course there is a congenital problem of the enzyme or of HB.Hope this answers your query.Best wishes.
