Why is the 24-hour urine protein quantification too high and the 24-hour urine microalbumin normal?

The 24-hour urine protein quantification is high but the microalbumin is normal, indicating that the protein in the poster’s urine is not mainly albumin. It is best for the poster to do a urine protein electrophoresis analysis to check for other substances in the urine. Whether the content of protein (such as transferrin, globulin, etc.) exceeds the standard. Glomerular proteinuria is dominated by microalbumin (medium molecule), while tubular proteinuria is dominated by small molecule proteinuria. If the results of urine protein electrophoresis show mainly small molecular proteins, it indicates renal tubular damage.
