24-hour urine protein is mainly through the collection of 24 hours of urine, to determine the content of protein, under normal circumstances in 24 hours of protein content of 150 mg or less; 24 hours of urine protein greater than 150 mg of total protein is called proteinuria.
The causes of proteinuria are mainly pathologic and physiologic. Pathologic causes include glomerular proteinuria, tubular proteinuria, mixed proteinuria, and histiocytic proteinuria; physiologic causes include exercise, fever, and body position.
