Normal Reference Range:

• BUN:Creatinine Ratio: 10:1 to 20:1 Red Cliff Labs

Test Components:

• BUN (Blood Urea Nitrogen): A waste product filtered by the kidneys; elevated levels may indicate kidney dysfunction.

• Creatinine: A waste product from muscle metabolism; elevated levels can signal impaired kidney function.

Clinical Applications:

• Assessing Kidney Function: Helps determine the kidneys’ ability to filter waste.

• Diagnosing Renal Conditions: Identifies potential kidney diseases or dysfunctions.

• Evaluating Dehydration: An elevated ratio may suggest dehydration.

Interpretation:

• Normal Ratio (10:1 to 20:1): Indicates normal kidney function.

• Elevated Ratio (>20:1): May suggest prerenal azotemia, often due to dehydration or decreased blood flow to the kidneys.

• Low Ratio (<10:1): Could indicate intrarenal causes, such as acute kidney injury or chronic kidney disease.

Next Steps:

If your BUN:Creatinine Ratio is outside the normal range, consult with your healthcare provider for further evaluation and appropriate management.
