Labs look at urine protein indicators, mainly urine routine and 24-hour urine protein quantitative, in addition to urine microalbumin can also be in the early response to the situation of urine protein. To determine whether or not there is urine protein or how much urine protein there is, you need to look at the urine routine and 24-hour urine protein quantitative, the former is qualitative, the latter is quantitative. A positive urine protein in the urine routine is shown by a plus sign. Negative indicates that no significant urinary protein was measured; the more positive plus signs, the more severe the degree of urinary protein. Generally, the highest grade of urine protein in a routine urine test is 3 or 4 plus signs. 24-hour urine protein quantification is the gold standard for determining the degree of urinary protein. 24-hour urine protein quantification less than 0.15g or less is within the normal range. 0.15~1.0g belongs to mild, proteinuria 1.0~3.5g belongs to moderate proteinuria, and if 24-hour urine protein quantification is more than 3.5g, it belongs to a large amount of urinary protein. Note that determining kidney disease does not only depend on urine protein, but also need to look at kidney function, urinary tract ultrasound and other tests, need to visit the doctor for a full interpretation.
