When your BUN levels are compared with your creatinine levels, it gives a fuller picture of what’s happening with your kidneys. This is known as the BUN/Creatinine ratio. Creatinine is a waste product from your muscles that is also filtered by your kidneys.
Why would BUN be slightly elevated? A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level.
Your BUN value of 11 mg/dL is normal. A good Blood urea nitrogen (BUN) is usually between 7 and 20 mg/dL. Your kidneys perform several essential jobs for your body, including filtering the blood, regulating electrolyte levels, and producing hormones.

Generally, a high BUN level means your kidneys aren't working well. But elevated BUN can also be due to: Dehydration, resulting from not drinking enough fluids or for other reasons. Urinary tract obstruction. Congestive heart failure or recent heart attack.
Elevated creatinine level signifies impaired kidney function or kidney disease. As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance of creatinine by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys.
