@dablues - Have you discussed the BUN results with your doctor? Here's some information I found on the test.

"Normal BUN levels can vary, but generally a high level of blood urea nitrogen is a sign that your kidneys are not working correctly. However, abnormal results don't always indicate that you have a medical condition needing treatment. Higher than normal BUN levels can also be caused by dehydration, burns, certain medicines, a high protein diet, or other factors, including your age. BUN levels normally increase as you get older. To learn what your results mean, talk to your health care provider." -- BUN (Blood Urea Nitrogen): https://medlineplus.gov/lab-tests/bun-blood-urea-nitrogen/
