Detailed explanation-1: -In general, about 7-20 mg/dL is a normal level. A higher than normal BUN level may be a sign that your kidneys are not working well. Your doctor will compare your BUN results along with other test results, such as creatinine and eGFR (estimated glomerular filtration rate), to decide on next steps.
Detailed explanation-2: -There is wide range of urea clearance in normal persons. Normal maximum clearance varies from 60 to 95 ml/min, with an average of 75 ml/min. The normal standard urea clearance varies from 40 to 65 ml/min with an average of 54 ml/min.
Detailed explanation-3: -What are normal levels: The ratio of BUN to creatinine is usually between 10:1 and 20:1. A healthy individual typically has serum BUN levels higher than serum creatinine levels. A measurable increase in the serum creatinine levels in hospitalized patients is indicative of Acute renal failure (ARF).
