The ratio of urinary protein to urinary creatinine, its reference range is 0-30. If it is within this range, it means there is no proteinuria and the kidney is normal. If it is between 30-300, it means there is a small amount of proteinuria. If it is greater than 300, it means there is a large amount of proteinuria. The advantage of this test is that it is a relatively accurate assessment of how much protein is in the urine, and is parallel to the 24-hour urine protein quantification. If the ratio of urine protein to urine creatinine is normal, the 24-hour urine protein quantification will also be normal. The advantage of this is that it is easy to take, and it is usually enough to check the morning urine, which is not as complicated as taking a 24-hour urine protein quantification. After the appearance of urine protein often represents a kidney injury, you need to go to the nephrology department of the hospital for further consultation, to assess the severity of kidney disease, according to the relevant results, targeted medication.
