“Proteins in urine” (proteinuria) indicates a problem in the kidneys. The maximum permitted protein level in the urine is 30mg/dl. If there are proteins found in the urine, the follow-up procedure is to examine urine collected over 24 hours. There should be no more than150mg of proteins in urine excreted over a 24 hour period. If the urine-protein level is above 3,5g/24h urine your daughter may be experiencing glomerulonephritis. However, other parameters of the kidneys’ function need to be examined, as well: the creatinin, urea, urinary sediment, blood pressure etc. There are few conditions wherein protein presence in the urine is normal such as: functional proteinuria (in cases of high temperature or great physical efforts), idiopathic transitory proteinuria, intermittent proteinuria, and/or orthostatic proteinuria.
