I too have low iron saturation (13.3).  My Hemoglobin is 10.9 and Hematocrit 34.3.  I have been having this problem off and on for the past three years.  In Sep 10, I had Typhoid and everything dropped but came back up.  In Nov 12 - Jan 13, I had Whopping Cough and everything dropped again.  Getting ready to have a scope done to see if I am losing blood somewhere (had a Gastric By-Pass in Mar 05) and then dr talking about IV Iron.  Question.  Today I found out my Chest X-Ray from Tuesday was abnormal, and until I speak with my PCM, I dont have a clue.  Just wondering if it could be my heart (I had a stent since Sep 01) or something else.
Hello, Thanks for the query to Chat Doctor. Forum. Why not upload, X-ray report with query? Whooping cough usually develops anti-antibody hence, a self limiting immunity develops in body and patient cured within 40-50 days without any Chat Doctor. In X-ray may be some lesion, may be enlargement of heart Hemoglobin is low, but, what is the cause? What is the iron binding capacity ? Report upload. Good luck.
