Positive urine protein indicates kidney damage, and this condition is generally not self-healing. Further examination of urine protein quantification, kidney ultrasound, creatinine and urea are needed to determine the kidney function. For those with small protein quantification, ACEI or ARB drugs can be applied to reduce urine protein, and at the same time, the kidney can be protected with Chinese medicine such as Bailing Capsules and Haikun Renxi. For large urine protein quantification, additional hormone or immunosuppressant treatment is needed to prevent further kidney damage. In case of acute renal impairment or acute glomerulonephritis, treatment may involve plasma exchange, hemodialysis and other special treatment modalities. Therefore, if you have positive urine protein, you must go to the nephrology department of a hospital to get a clear diagnosis and then use targeted medication.
