What is a GI bleeding scan?

A GI bleeding scan is an imaging test that can help detect the origin of your child's gastrointestinal bleeding.

During the test, blood will be drawn from your child's vein. The drawn blood will be mixed with a radiopharmaceutical called Technetium-99m. The blood cells will then be reinjected into your child's vein by the same technologist who took your child’s blood.
