Hi hellokelli,
What Zaini said is correct. If your Hb is chronically low, your body can compensate by increasing bone marrow activity, which in turn causes an increase in iron absorption through the gut. This may be happening if these iron levels are a recent phenomenon. Do you have previous iron tests to compare with these?
You should periodically have the iron panel tests run to assess if there is any further upward movement in your levels. Your levels are no danger now, so if they don't continue to rise, there will be no concern. If they do, you may have to watch your diet and eat a low iron diet, but make sure you are getting plenty of B vitamins if you do have to adjust your diet. With thal minor, B vitamins play an important role in maintaining Hb level, so it is important to make sure your diet is good and you should consider a daily supplement. If you can find a way to bump your Hb level up slightly it will decrease any excess iron absorption taking place.
