From Citizendium, the Citizens' Compendium
In medicine, proteinuria is "the presence of proteins in the urine, an indicator of kidney diseases."[1]

Diagnosis
Spot protein/creatinine ratio
One study found that in the presence of stable renal function, a protein/creatinine ratio:[2]
- > 3.5 (mg/mg) indicates nephrotic-range proteinuria
- < 0.2 is within normal limits
Spot urine albumin/creatinine ratio
In adults, albuminuria is a more sensitive than total protein in detecting chronic kidney disease from many glomerular diseases.[3]
- <30 mg/g is a normal albumin-creatinine ratio
- 30-300 mg/g is microalbuminuria
