What do the 24 hour Urine Protein tests assess?

The 24-hour urine protein test is specifically designed to assess kidney function by measuring the amount of protein excreted in urine over a full day. It helps healthcare providers determine if there is an abnormal amount of protein in the urine, which can indicate potential kidney issues such as kidney disease or glomerulonephritis. When kidneys are functioning properly, they typically filter out waste while retaining proteins necessary for body functions. An elevated level of protein in the urine may suggest that the kidneys are not filtering properly, serving as a crucial diagnostic tool for assessing kidney health.
