I went to the doctor because I was losing hair in clumps in the shower, lots in the brush, I also have fatigue, shortness of breath, chest pains, weakness, restless legs, cold, irregular periods, and many more things, so she started in about my thyroid right away but I have a different expert for that and that was checked in January and thats fine. So she ran some test and they sent me a letter saying all labs were normal but as I was looking at them one popped up Ferritin well I didn't know what this was so I looked on the computer, and well I think with all these symptoms I could be Irom Deficient My Ferritin Level is 15.1, I'm a 30 year old female. What are normal Ferritin Level Range?
