The standard 24-hour urine protein quantification is 0.15g/24 hours. That is, under normal circumstances, the maximum amount of urine protein should not exceed 150mg/ 24 hours. Patients with 24-hour urine protein are generally advised to remove all of the overnight urine from the previous day, and then keep all of the urine until the next morning when all of the overnight urine is concentrated, then mix it in a container, mix it, measure it, write down approximately how many milliliters of urine there are, shake it well, and then send a tube to the hospital for laboratory testing. When the hospital examines this, the amount of urine protein in their urine for 24 hours is calculated by multiplying the amount of urine protein in this tube of urine by the entire amount of urine provided to the hospital in question. There are many reasons why it is difficult to retain accurate urine protein in a patient’s 24-hour urine during that process. Therefore, many hospitals now use urine protein creatinine instead of 24-hour urine protein quantification, i.e., they draw the patient’s urine at one point in time and then measure the ratio between the urine protein and creatinine values, which is more convenient and easier to measure accurately.
