I wonder if somebody could please interprete these Ferritin results for me 13ng/mL*. 20-204ng/mL. A doctor put my mother on 305mg of iron tablets twice a day. Her own doctor returned from leave and said she wasn't even aenemic and to stop taking them. I am so worried as she has had a bleeding ulcer in the past! Thanks in advance I know it is not entirely thyroid related but I am currently so unwell with my thyroid right now and am unable to get to her!
