"The healthy range of serum ferritin lies between 20 and 80 ng/ml. Below 20, you are iron deficient, and above 80, you have an iron surplus. Ferritin levels can go really high. I’ve seen levels over 1,000, but anything over 80 is likely going to be a problem." http://articles.mercola.com/sites/articles/archive/2009/12/15/Interesting-Nov...
