Actually, blood urea nitrogen is just same to creatinine level, it won’t increase until half of renal function has been damaged. Glomerular Diseases. When high BUN level is considered to be dangerous? Blood Urea Nitrogen (BUN) levels are tested to verify the function of kidneys. BUN levels are raised when any damage is caused to liver or kidneys. Creatinine clearance can help clarify the extent of kidney damage and if one or both kidneys are diseased 1. The normal BUN level ranges from 3.5-7.1mmol/L (9-20mg/dL).
