Normally, the presence of casts in the urine is considered to be an unusual finding. However, small amounts of hyaline casts (between 0–2 casts per low power field of the microscope) may be detected in the urine of healthy individuals without necessarily indicating a serious condition like kidney disease.
What do casts in urine indicate?
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.
Which condition promotes the formation of casts in the urine?
The following factors promote the formation of casts in the kidney: Larger than normal amounts of plasma proteins entering the tubules. Decreased pH. Decreased urinary flow rate.
How are urinary casts formed?
Casts: Urinary casts are cylindrical structures that are formed from coagulated protein (Tamm-Horsfall protein) secreted by tubular cells. As their name implies, they are usually formed in the long, thin, hollow renal tubules and take their shape. They develop in the distal convoluted tubule or the collecting duct.What are casts?
A cast is a hard bandage that keeps part of the body from moving so it can heal.
What causes uric acid crystals in urine?
Uric acid stones form when the levels of uric acid in the urine are too high, and/or the urine is too acidic on a regular basis. The formation of these types of stones can run in families. Inherited problems in how the body processes uric acid or protein in the diet can increase the acid in urine.
How do I report a cast to urine?
General interpretation. Casts are quantified for reporting as the number seen per low power field (10x objective) and classified as to type (e.g., waxy casts, 5-10/LPF). Casts in urine from normal individuals are few or none (and are usually hyaline or granular in nature).

Article first time published onWhy do casts form?
They form via precipitation of Tamm–Horsfall mucoprotein which is secreted by renal tubule cells, and sometimes also by albumin in conditions of proteinuria. Cast formation is pronounced in environments favoring protein denaturation and precipitation (low flow, concentrated salts, low pH).
Where do casts form?
Casts are cylindrical bodies formed either in the distal convoluted tubules or the collecting ducts of the kidney. Since the walls of the tubule act as a mold for cast formation, the width of the tubule determines the width of the cast.
