[|Human|] Can you have an insufficient iron level in your blood and your blood test comes up with a normal iron content? I am severely allergic and having to take shots for allergy and antihistimine right now. I am unable to eat many foods - fruits and vegetables until th first frost. I have lost  50 pounds. I also cant take vitamins or minerals anymore since the allergy started in February of this year. I used to take iron and it really helped me cope...now I cant take anything. could you tell me what I can do about an iron supplement. I am faint every day just about and weak. Much of this is allergy but much is the low iron I have in my system now.
[|AI|]  Serum Iron is a pretty poor predictor of iron deficiency, so yes, you could be deficient even if this value in your blood test is normal. The best test would be a full blood examination including He, MTV, MHC, RDW and serum ferritin levels. (Serum ferritin measure Iron stores)From these tests, your doctor will be able to tell if you are truly iron deficient. Iron supplements vary based on the amount of elemental iron they have in them. The more iron, the stronger the effect and the stronger the side effects (constipation etc.). If you have multiple allergies I would go for a pharmaceutical iron preparation as opposed to a "natural" Iron remedy. One last thing - the weight loss is pretty severe and It's hard to blame allergies or iron deficiency. Make sure you doctor checks this out fully.
