<<Disclaimer: Verify this information before applying it to your situation.>> Hi... Thanks to all the responses that I recieved with regard to low ferritin levels. It turns out my daughter, who is 12 does have CD. I'm not sure what they will do about the low level yet. They did lots of blood work on her and one of the tests turned out strange. Her phosphorus level was high. Does anyone know what can cause this. They asked me if she drinks lots of millk. Currently she does not because it bothers her tummy. Thanks for the help.
