text_1: I have a patient with a low hemoglobin 6 weeks ago.  Yesterday I saw him for a viral illness and his total serum iron was worse (down to 10 from 16), but the total iron binding capacity was lower and now in the normal range.  Am I missing something here?  Or could it still be iron deficiency?
text_2: Is low serum iron and normal iron binding capacity consistent with iron deficiency anemia?
