Urine protein 2+, kidney function is normal, can be seen in physiological factors such as after strenuous exercise, usually no special treatment, after removing the cause can return to normal; also can be seen in pathological factors such as acute and chronic glomerulonephritis, pyelonephritis, interstitial nephritis, nephrotic syndrome and other diseases, usually through the use of medication (such as levofloxacin), such as treatment. 1. Physiological factors: such as sudden strenuous exercise, standing for a long time, etc., may cause transient proteinuria, which usually does not require special treatment, and can be returned to normal after removing the causative factors. 2. Pathological factors: urine protein 2 +, normal renal function can also be seen in acute and chronic glomerulonephritis, pyelonephritis, interstitial nephritis, nephrotic syndrome, lupus nephritis, hypertensive nephropathy, diabetic nephropathy and other diseases. Usually, drugs such as levofloxacin, ciprofloxacin and other anti-infective treatments; angiotensin-converting enzyme inhibitors such as captopril and benazepril to lower blood pressure and protect kidneys; glucocorticosteroids such as methylprednisolone and immunosuppressants such as cyclophosphamide can be used to control the condition as prescribed by the doctor. If there is urine protein 2+, but renal function is normal, it is recommended to consult a doctor in time to find out the reason and follow the doctor’s instructions to standardize the treatment.
