is there a scale for protein in the urine
a JustAnswer user. Proteinuria (protein in the urine) can be related to any number of factors in children, but it can also be a transient finding that resolves on its own without any further complications. It is measured on a scale to 4+ (by this sort of test, at least), with 1+ being the least amount of protein. Proteinuria can be caused by a number of different factors. Sometimes, after a bacterial or viral infection the kidneys can become irritated and this can lead to proteinuria.
