From the Research
A BUN level of 36 mg/dL is indicative of potential kidney dysfunction or impaired renal function, suggesting that the kidneys are not effectively filtering waste products from the blood. This elevation can be caused by various conditions, including acute or chronic kidney disease, dehydration, congestive heart failure, gastrointestinal bleeding, high-protein diet, or certain medications like NSAIDs or diuretics 1. The normal range for BUN is 7-20 mg/dL, and a level of 36 exceeds this range, signaling a need for further evaluation. Key considerations for interpreting a BUN level of 36 include:
- Dehydration, which can concentrate the blood and elevate BUN levels
- Medications that affect kidney function, such as NSAIDs or diuretics
- Underlying conditions like heart failure, diabetes, or kidney disease
- The importance of interpreting BUN levels alongside creatinine levels and other kidney function tests for a comprehensive assessment. Given the potential implications of an elevated BUN level on morbidity, mortality, and quality of life, it is crucial for individuals with a BUN of 36 to seek medical evaluation promptly to determine the underlying cause and appropriate treatment, as discussed in the context of abnormal basic metabolic panel findings and their implications for nursing practice 1.
