General Information

An iron stain for urinary haemosiderin is indicated when a patient’s condition suggests the possible presence of haemolysis.


Assay Limitations:

If the test Haemosiderin is present in small amounts or is unevenly distributed, the test should be repeated on a freshly taken sample.

The observation of renal epithelial cells or casts which contain Haemosiderin granules is a useful indicator that the Haemosiderin originated in the kidney and is not a contaminant.
