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

Contents

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
