What is it?

This test measures the amount of iron in your child's blood. Too little iron can cause anemia, which can cause weakness, tiredness, or lack of stamina. Too much iron can cause hemochromatosis. This disease usually is passed down in families. It can cause tiredness, weakness, liver problems, and pain in the joints.

Why is this test done?

An iron test is done to:

  • Check for too much or too little iron in the blood.
  • See if your child's diet is providing enough iron.
  • Find out if treatment to keep the right amount of iron in your child's blood is working.

How do you prepare for the test?

  • Tell your doctor if your child has had a blood transfusion.
  • Check with your doctor if any other preparation is needed.
