Urine protein quantification generally involves retaining urine for 24 hours to determine protein quantification. It generally requires a period of retention from 7:00 a.m. to 7:00 p.m. The urine excreted during this time period is collected in a clean container. Sampling requires mixing before sampling. It should be noted that it is recommended to collect urine for 24 hours after the urine is drained at 7:00 a.m. It is important to strictly control the time for 24 hours, and not to decrease or increase the time of retention arbitrarily, and the amount of water consumed during the retention period should be the same as that of the normal time, otherwise it may affect the accuracy of the quantification of urinary proteins. The choice of container is also important, it is recommended to choose a suitable container, and the container should be clean and dry, it is recommended to put in a cool place. For female patients, it is recommended to avoid the menstrual period when taking urine protein quantification. Urine protein quantitative abnormal patients, it is recommended to regular hospitals, under the guidance of physicians standardized treatment.
