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.
Haemosiderin either appears as blue staining of isolated or grouped granules. Results are reported as POSITIVE or NEGATIVE
