I am a 52 year old female. I have been anemic for many years. I had a colonoscopy and endoscopy which both resulted in a clean record some 4 years ago. I have had heavy menstrual periods and this seemed to be the contributing factor to the anemia. However, the periods have subsided greatly. My main concern is that my Iron Saturation is a 4, Iron Serum is 17, TIBC 453, UIBC 436, Hemoglobin 10.1 (the highest it has been in years.), Hematocrit 34.4, MCV 70, HCH 20.6, MCHC 29.4, RDW 18.4. My question is should some additional tests be done to discover why the saturation is so low? This has been low the past 2 years. In healthcare today it seems that you almost have to direct some of your own care proceedings. Is this saturation level something that I should be concerned about? I have read that it could mean that the iron is feeding some cancer or bacteria. What should be my next step? I just don't feel well a lot of the itme.
