II. Indication

  1. Monitor persistant Proteinuria

III. Efficacy

  1. More accurate than 24 Hour Urine Protein collection
  2. Most accurate if first morning void is used

IV. Technique: Random urine collection

  1. Urine Creatinine in mg
  2. Urine Protein in mg
  3. Calculate Urine Protein mg to Urine Creatinine mg Ratio

V. Interpretation: Urine Protein to Urine Creatinine Ratio

  1. Child under age 2 years
    1. Normal Ratio <0.5
  2. Adults and children over age 2 years
    1. Normal ratio <0.2 grams protein per gram Creatinine
    2. Nephrotic Ratio >3.5 grams protein per gram Creatinine
  3. Estimation of total protein
    1. Total protein (g/m2/day) = Upr/Cr * 0.63
    2. Abitbol (1990) J Pediatr 116(2): 243-7 [PubMed]

VI. Interpretation: Urine Albumin to Creatinine Ratio

  1. Normal Ratio (in general <30 mg/g is normal)
    1. Men: < 0.017 (or 17 mg albumin to 1 gram Creatinine)
    2. Women: <0.025 (or 25 mg albumin to 1 gram Creatinine)
  2. Microalbuminuria: 30-300 mg albumin/g Creatinine
  3. Macroalbuminuria: >300 mg albumin/g Creatinine
