Urine protein 3 +, blood creatinine normal may be intense exercise and other physiological conditions and nephrotic syndrome, asymptomatic proteinuria and other pathological conditions caused by.
1. Physiological proteinuria: after strenuous exercise, fever or change of body position, there is an increase in the foam in the urine, proteinuria is found in the examination, and the later review is mostly normal, which is mostly suggestive of physiological proteinuria.
2. Nephrotic syndrome: in nephrotic syndrome, the molecular barrier of glomerular filtration membrane and the charge barrier are damaged, the protein in the original urine increases, and a large amount of proteinuria is produced, but the kidneys are generally not damaged in the early stage, so that the renal function is normal and the blood creatinine is normal.
3. Asymptomatic proteinuria: clinically asymptomatic, mostly proteinuria is found in the examination, blood biochemistry shows normal renal function, generally a better prognosis, no special treatment, need for regular review, if necessary, can improve the renal puncture biopsy.
There are many other reasons why urinary protein 3+ but normal creatinine, you need to go to the hospital to find out the cause of the disease, and follow the doctor’s advice and active treatment.
