No: BUN stands for blood urea nitrogen and is a test of renal function. It used in conjunction with the creatinine level to evaluate the functioning of the kidneys. The BUN can be elevated from kidney disease, dehydration or a GI bleed. Always talk to your doctor about the clinical significance of your test results. Your BUN result is not clinically significant. Other tests are used to evaluate liver.
