The division of a tissue cylinder from percutaneous renal biopsy into several unequal parts for routine biopsy, ultrastructural analysis, and immunohistochemistry may infrequently cause ab- sence of glomeruli rendering the slides for immunohistochemical staining unusuitable. Instead of previously stained hematoxylin and eosin slide serving for checking up of the presence or absen- ce of glomeruli defrayed by Health Care Insurance Companies the proposed additional control cryostat slide was stained by the Sudan Red stain. Such slides were fully accepted by the Insurance authorities and providing information of the presence and number of glomeruli have eliminated the need for a control hematoxylin and eosin stain. This saved time and expenses and at the same time brought information on the presence, degree and location of steatosis
