A normal value for total urine protein is a 24-hour excretion of 150 mg or less. Among the proteins excreted through the kidneys are two types of proteins: the first, albumin; and the second, globulin. Together, these two are the total protein. When the kidney’s filtration membrane is undamaged and relatively intact, less protein is lost from the kidneys, and the total amount of protein in the urine in a 24-hour period is under 150mg. If the kidney’s filtration membrane is damaged, such as having chronic nephritis, acute nephritis, purpura nephritis, lupus nephritis, etc., then the protein lost from the kidney’s filtration membrane will increase, and the quantitative amount of urinary protein in 24 hours will be more than 150mg, or even more, and some of them have reached the standard of nephrotic syndrome, and the amount of excretion in 24 hours reaches more than 3.5g. For these cases, it is necessary to actively search for the cause of the disease and treat it from the cause, so as to achieve the purpose of repairing the renal filtration membrane.
