2025年3月4日 · In most cases, red blood cell casts reflect damage to the glomerulus, known as glomerulonephritis, or the presence of a microscopic bleeding within the kidney. White blood cell casts are typically associated with an underlying kidney infection (such as pyelonephritis) or inflammatory processes.

Most people with kidney lupus (lupus nephritis) will have an abnormal urinalysis. Protein, urine casts (especially red blood cell casts), red blood cells, or white blood cells in the urine can …
