Answer

The presence of dysmorphic red blood cells (RBCs), albumin, or RBC casts suggests glomerulonephritis as the cause of renal failure. Waxy or broad casts are observed in all forms of chronic kidney disease (CKD), including chronic glomerulonephritis. Low urine specific gravity indicates loss of tubular concentrating ability, an early finding in persons with CKD. See Urinalysis.
