Hansel stain
Stains structures containing iron
Identifies urinary eosinophils
Identifies yellow-brown granules of hemosiderin in cells and casts
Identifies urinary eosinophils
Modified Sternheimer Malbin
The dye is absorbed well by WBCs,
epithelial cells, and casts, providing
clearer delineation of structure and
contrasting colors of the nucleus and
cytoplasm

Hyaline cast appears as pink
Motile bacteria are unstained
Non-motile bacteria stains purple
T.vaginalis stains Light blue-green
