Proteinuria: if meeting any of the following conditions: 3 routine urine tests within 1 week qualitatively indicate positive urine protein; 24h quantitative urine protein >150 mg or urine protein/creatinine (mg/mg)>0.2; Urinary microalbumin was higher than normal for 3 times within 1 week. Very few children in the acute course of allergic purpura 6 months later, recurrent purpura, hematuria and/or proteinuria for the first time, should be sought for renal biopsy, such as IgA mesangial mesangial proliferative glomerulonephritis, can still be diagnosed as purpura nephritis. 2. 24-hour urinary protein quantification of 0.5 to 1.0g/1.73m2, and the total amount does not exceed 1.0g (to be quantified in non-infectious conditions); 3.
