A blood cast is an agglomerate of proteins which contain red blood cells or red blood corpuscles, and it has a cylindrical shape. The blood casts are formed in the kidneys and are the cause of blood in the urine, a phenomenon called hematuria. The presence of blood casts in urine is usually symptomatic of a malfunction of the renal glomuri which are gatherings of small blood vessels located above the nephron, the basic structural and functional unit of the kidney. Various sicknesses affecting the renal glomuri are grouped under the name glomerulonephritis. The treatment depends on the specific nature of the disease.
