BUN Creatinine Ratio
Measures renal function.
Management
- Normal BUN:Creatinine ratio values are generally 10-20.
- If BUN:Cr >20, this may be a sign of prerenal azotemia. If clinically appropriate, consider additional workup to determine cause.
- BUN can be impacted by other physiologic processes outside of the kidney; a BUN value alone should not be used as the sole indicator of renal health.
