Gomori’s Prussian Blue Iron Reaction

Formalin-fixed, paraffin embedded tissue block or cell block, or 1 unstained charged slide for each test requested plus 3-4 additional unstained slides cut at 4 microns. Adequate space on each slide for control tissue is required.

This stain is used to detect loosely bound ferric iron in tissue sections. It is sensitive enough to demonstrate minute amounts of iron deposits in blood cells, bone marrow and spleen.
