For 24-hour urine protein quantification, the report card will have the amount of protein per liter, the total urine volume, and the 24-hour urine protein quantification.The 24-hour urine protein quantification is the amount of proteinuria per liter multiplied by the total urine volume. When the 24-hour urine protein quantification result exceeds 150 mg, you can be said to have proteinuria. When looking at the 24-hour urine protein quantification form, it is also important to note the amount of urine; when the amount of urine is too little, such as less than 1,000 ml, or too much, such as more than 3,000 ml, it may affect the results of the 24-hour urine protein quantification. If the 24-hour urine protein quantitative 150~1000mg, it is mild urinary protein; 24-hour urine protein 1000~3500mg is moderate urinary protein; greater than 3500mg is a large amount of urinary protein, which belongs to the range of renal disease urinary protein. The cause of proteinuria is divided into physiologic proteinuria and pathologic, physiologic proteinuria is a transient proteinuria due to cold, fever, high protein diet, late night and other factors. In this case, lifting the trigger can be restored. Pathologic proteinuria is due to various causes of primary or secondary kidney disease, common are all kinds of nephritis, such as acute nephritis, chronic nephritis, lupus nephritis, purpuric nephritis, etc., as well as various causes of nephrotic syndrome and so on. In addition, diabetic nephropathy and hypertensive kidney damage are also prone to proteinuria. When the result of 24-hour urine protein quantification is abnormal, it is recommended to go to regular hospitals and standardize the treatment under the guidance of physicians.
