The diagnosis of uremia is not based on the amount of urine protein, but on the amount of creatinine and glomerular filtration rate. If the creatinine exceeds 707umol/L or the glomerular filtration rate is less than 10mL/min, then uremia can be diagnosed. Some patients with particularly high amount of urine protein, such as 24-hour urine protein quantification even reaches 10g, but the patient’s creatinine and glomerular filtration rate are normal, this situation only suggests that the patient is suffering from nephrotic syndrome, not having uremia. Some patients with uremia may have very little 24-hour urine protein quantification, below 500mg, which is basically close to normal, but the patient’s creatinine has exceeded 707umol/L and the glomerular filtration rate has been below 10mL/min, which is also uremia. In other words, urine protein is a factor of kidney damage, but not a criterion of uremia. If you suspect that you have uremia, it is recommended to check the kidney function to see if the creatinine reaches this index mentioned above, and you can also perform ECT examination of both kidneys to measure the glomerular filtration rate.
