RBC Cast

Slide 11

August 2009

This is an example of a red blood cell cast. The red cells can be differentiated by their clear outline, which is most clearly seen in the middle of the cast. A red cell cast should indicate ongoing glomerulonephritis. In this circumstance, one might also expect to find free red cells in the urine. Sometimes these red cells become damaged while being squeezed through glomerular holes and end up dysmorphic or misshapen. In addition to red cells and red cell casts, one would expect to find abnormal amounts of urinary protein and albumin in patients with glomerulonephritis.
