Granular casts are a sign of many types of kidney diseases. Red blood cell casts mean there is a microscopic amount of bleeding from the kidney. They are seen in many kidney diseases. Renal tubular epithelial cell casts reflect damage to tubule cells in the kidney.

Can granular casts be normal?

Casts in urine from normal individuals are few or none (and are usually hyaline or granular in nature).

What does it mean to have casts in your urine?
