I happen to really familiarize myself with the kidneys and research them because the auto inflammatory condition I have can cause secondary amyloidosis, deposits in the kidneys, heart, etc but the kidneys tend to be the number 1 most damaged organ with my condition and one of the largest reasons for such a lower average lifespan. So I do what I can to help them while still living life and essentially what that comes down to is most importantly, drinking a lot of water every day. Try to not get super dehydrated, don’t eat too many things containing oxalates without pairing it with dietary calcium (not supplemental). I keep my protein at 1g per pound and my creatinine is very close to yours. Your liver enzymes are just a tad high but it wouldn’t even be considered a concerned elevation by itself, it’s not that high. Like I said, speak to the doctor about the bilirubin and your BUN. I am interested to hear his opinion and how he may be able to bring the BUN down to around the same average as the creatinine. You may be able to do it yourself by hydrating and waiting a couple weeks for a blood test. Sometimes the body surprises you and your BUN will go from the max end of the high range to within the optimal range. The great news is that your liver enzymes are not bad, they are ok and your creatinine makes your kidneys look pretty good, however common sense would want anyone to know why your BUN is at the max of the reference range when your creatinine is great by itself.
P.S you can search up BUN/Creatinine ratio calculators and enter your values and see what they are. I also haven’t seen your egfr and don’t want to rely on another calculation. Can you find that in your bloodwork?
