Urine protein 3 plus hospitalization?

Urine protein 3+, recommended hospitalization. Under normal circumstances, urine routine examination, urine protein is negative. If urine protein positive may be caused by urinary tract infection, renal insufficiency, chronic glomerulonephritis, nephrotic syndrome and other diseases, need to further urine protein quantitative examination and renal function test to make a clear diagnosis. In clinical work, normal urine protein such as less than 2+, do not consider renal failure caused by urine protein increase, may be related to infection, trauma, etc. But if the urine protein plus more than 2, more than 2, normal and kidney filtration membrane damage, filtration membrane damage, resulting in protein leakage into the urine, resulting in increased urine protein.
