Urine protein 3+, urine occult blood 2+, generally consider nephritis or nephrotic syndrome, minor tubular injury, nutcracker syndrome, etc.; need to receive further renal function tests to clarify the diagnosis. 1. Nephritis: Nephritis can lead to impaired renal function, which in turn causes a decline in glomerular filtration function, resulting in the leakage of large molecules into the urine, such as red blood cells and proteins, causing proteinuria and hematuria. 2. Nephrotic syndrome: Nephrotic syndrome will lead to renal metabolic disorders, which will lead to protein can not be completely absorbed, then lead to a large number of proteins into the urine, resulting in proteinuria; renal inflammation, will lead to the urinary system induced hemorrhagic symptoms, resulting in urinary occult blood phenomenon. 3. Slight renal tubular injury can also appear urine protein, urine occult blood positive, improve the examination to clarify the cause of the disease, to take a better treatment strategy. 4. Nutcracker syndrome: patients may also have hematuria, proteinuria, Nutcracker syndrome and venous vascular dysplasia. In the absence of renal impairment, it can be left untreated for the time being and followed up regularly for observation. In conclusion, proteinuria and urinary occult blood has more reasons, it is recommended that patients go to the hospital in a timely manner, under the guidance of the doctor to clarify the cause of the disease, and timely compliance with medical treatment.
