Your Urine Test Results Are Normal

Your protein-to-creatinine ratio of 0.11 (110 mg/g) is within the normal range and does not indicate kidney disease. 1, 2

Understanding Your Results

  • Normal threshold: The KDIGO (Kidney Disease: Improving Global Outcomes) guidelines define normal protein excretion as a protein-to-creatinine ratio <150 mg/g (or <0.15 mg/mg). 2

  • Your value of 0.11 (110 mg/g) falls comfortably below this cutoff, indicating that your kidneys are filtering protein appropriately. 1, 3

  • Healthy reference data: In a study of 60 healthy adults, the protein-to-creatinine ratio never exceeded 100 mg/g (0.10 mg/mg) in the absence of exercise, fever, or urinary tract disease. 3 Your value of 110 mg/g is just slightly above this very conservative threshold but still well within the accepted normal range of <150 mg/g used in clinical practice. 2

What These Numbers Mean

  • Urine protein 9.4 mg/dL: This represents the concentration of protein in your urine at the time of collection. 1

  • Urine creatinine 85.9 mg/dL: This represents the concentration of creatinine (a muscle breakdown product) in your urine. 1

  • The ratio (0.11 or 110 mg/g) corrects for urine concentration and provides a more accurate estimate of your actual daily protein excretion than either number alone. 1, 4

Clinical Significance

  • No kidney disease: A ratio <150 mg/g indicates normal kidney function and rules out clinically significant proteinuria. 1, 2

  • No further testing needed: If you have no other signs of kidney disease (such as elevated blood pressure, diabetes, or abnormal kidney function tests), no additional urine testing is required at this time. 1

  • Annual screening: If you have risk factors for chronic kidney disease—such as diabetes, hypertension, or a family history of kidney disease—annual urine protein screening is reasonable. 1

Important Context

  • Transient elevations: Even in healthy individuals, protein excretion can temporarily increase after vigorous exercise, during fever, with urinary tract infections, or during menstruation. 1, 5 Your normal result suggests none of these factors were present.

  • Pregnancy threshold: Note that in pregnant women, a higher cutoff of 0.3 mg/mg (300 mg/g) is used to define abnormal proteinuria. 5, 6 Your value would be normal even by pregnancy standards.
