Understanding BUN to Creatinine Ratio
The BUN to Creatinine ratio is a medical diagnostic tool used to assess kidney function and determine potential causes of kidney impairment. Blood Urea Nitrogen (BUN) and Creatinine are both waste products that healthy kidneys filter out of the blood.
Normal Ratio Range: 10:1 to 20:1 (or 10-20)
High Ratio (>20:1): May indicate conditions such as dehydration, congestive heart failure, gastrointestinal bleeding, or increased protein breakdown.
Low Ratio (<10:1 strong=""> May suggest liver disease, malnutrition, rhabdomyolysis, or syndrome of inappropriate antidiuretic hormone secretion (SIADH).
This calculator provides a quick assessment of your kidney health based on your lab results. However, it's important to consult with a healthcare professional for a comprehensive evaluation and diagnosis.
Frequently Asked Questions
What is BUN?
Blood Urea Nitrogen (BUN) measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is produced when protein is broken down in your body. Healthy kidneys filter urea out of the blood.
What is Creatinine?
Creatinine is a waste product produced by muscles from the breakdown of a compound called creatine. Creatinine levels in blood provide an indication of kidney function, as healthy kidneys filter creatinine from the blood.
What does the ratio indicate?
The BUN to Creatinine ratio helps differentiate between causes of kidney impairment. A high ratio may indicate problems before the blood reaches the kidneys, while a low ratio may suggest intrinsic kidney disease.
How accurate is this calculator?
This calculator provides a medically accepted formula for determining BUN to Creatinine ratio. However, individual health conditions may affect results. Always consult a healthcare provider for medical interpretation.
