RENAL INX-PROTEINURIA

From NeuroRehab.wiki

SUMMARY

1. Proteinuria is an important indicator of underlying renal pathology; normal 24-hour urine protein is < 150 mg.

2. Greater than 2 g/d indi­cates significant glomerular pathology.

3. Medullary cystic disease and obstructive uropathy are the only exceptions in which there can be pathology and a normal urine sediment with minimal proteinuria.

4. Transient proteinuria is common in people during a febrile illness, after strenuous exercise, and in patients with HF and COPD.

5. Estimated with spot urine protein:creatinine ratio.
