The normal value of 24-hour urine protein is <150mg/24 hours, and the results may vary depending on the machine. It is recommended to consult your local doctor. Urine protein is produced mainly due to the increase in permeability of the glomerular filtration membrane caused by damage to the glomerular mechanical and electrical barriers, followed by the production of urine protein. Patients need to accurately collect 24-hour urine and mix the urine well to calculate the amount of urine protein. 24-hour urine protein quantification <150mg is normal. If the urine protein is persistently >150mg/24 hours, it is called proteinuria. Elevated 24-hour urine protein is often indicative of tubular or glomerular damage, such as acute nephritis and interstitial nephritis. In addition, 24-hour urine protein quantification is also helpful in determining the condition and assessing the prognosis. If you have elevated 24-hour urine protein, it is recommended that you go to a regular hospital in time, complete the examination to identify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
