| Check items | normal value | clinical significance |
|---|---|---|
| Urine routine | Negative(-) | initial screening |
| 24-hour urine protein quantification | <150mg/24h | Accurately assess protein loss |
| Urine protein/creatinine ratio | <30mg/g | An easy alternative to peeing 24 hours a day |
| urine protein electrophoresis | - | Distinguish protein sources |
5. Prevention and treatment of proteinuria
1.basic treatment: Control blood pressure (target<130/80mmHg), blood sugar (HbA1c<7%)
2.Diet management: Moderate protein intake (0.8-1g/kg/d), limit salt
3.drug treatment: ACEI/ARB drugs have protein-lowering effects
4.Regular monitoring: High-risk groups should review urine routine every 3-6 months
6. Latest opinions of experts
Based on recent medical conferences and expert interviews, special emphasis is placed on:
• Urinary protein positivity needs to be distinguished between transient and persistent
