The Cholesterol (Urine) test measures the amount of cholesterol excreted in the urine. This test is less common than blood cholesterol tests and is primarily used to assess conditions affecting lipid metabolism, such as nephrotic syndrome, where cholesterol can be elevated in the urine due to kidney dysfunction. It may also help in diagnosing disorders related to cholesterol processing and excretion. The test can provide additional insights when evaluating lipid-related health concerns, particularly when a person has abnormal lipid levels or kidney issues.
