The 24-hour urine protein test checks how much protein is being spilled into the urine, which can help detect disease or other problems. The test is simple and noninvasive. Urine samples are collected in one or more containers over a period of 24 hours.
Urinary total proteins are negligible in healthy individuals. But levels are increased in diseases that impair renal function like Diabetes, Hypertension, Nephrotic syndrome and Drug nephrotoxicity.
