What should a patient be told with a microalbumin (Microalbumin) level of 18.3, urine creatinine (Urine Creatinine) of 174.9, and a microalbumin-to-creatinine ratio (MA/CR) of 10.5, indicating impaired renal function?

From the Guidelines

Your microalbumin-to-creatinine ratio of 10.5 mg/g is within the normal range (normal is less than 30 mg/g), indicating your kidneys are currently filtering proteins appropriately. This is good news as it suggests your kidney function appears healthy at this time, though we'll continue to monitor these values periodically as part of your routine health assessment to ensure early detection of any changes that might indicate developing kidney issues, as recommended by the standards of medical care in diabetes 1.

From the Research

Patient Information

  • Your microalbumin random result is 18.3, which indicates a potential issue with your kidney function.
  • Your urine creatinine level is 174.9, and your microalbumin-to-creatinine ratio (MA/CR) is 10.5, which is below the typical threshold for microalbuminuria 2, 3.

Interpretation of Results

  • According to a study published in the Journal of the American College of Cardiology, a lower MA/CR ratio is associated with better outcomes in patients with chronic kidney disease 4.
  • Another study published in the Clinical Journal of the American Society of Nephrology found that a MA/CR ratio of 10-19 was associated with the best outcomes in patients with chronic kidney disease 3.
  • It is essential to note that the MA/CR ratio can vary depending on several factors, including gender and comorbidities, and should be interpreted in the context of individual patient characteristics 2, 5.
