23 year old female, been taking iron pills and ferritin has increased from 7 to 34, but tibc remains high at 482. iron percent saturation is 37%. what kind of inflammation can cause high tibc and should i be concerned ?

You give a correct iron saturation this time. You have been taking appropriate iron supplement with improvement in ferritin and good iron saturation. TIBC remains high means that your body still needs iron supplement even with the improvement. I expect your anemia have improved, i.e. higher Hb, but you should continue with iron supplement. Cause of iron deficiency anemia needs to be fixed.

Inflammation does not increase TIBC, it is just an indication that you still need iron supplements. You should consult your doctor about the cause of your iron deficiency and address the cause. Wish you good health!
