When to worry about kidneys?

[Guest guest]

I find my BUN and Creatinine are very dependent on the

amount of water I have had the day before. Is this true for

everyone? If I drink 5-8 glasses of water, then I'm in

range. Otherwise I'm high on both. My major concern is

that I often have a 59 as my local lab eGFR reading. At

NIH, my chem panel eGFR was >60 but my " whole blood " eGFR

test was 59. I'm untreated with a very high WBC (>250k) so

am concerned both about my kidneys now and when I need

treatment. I know with my very high WBC, TLS is something

to be avoided.

Would appreciate the comments of anyone on an eGFR of 59.

Thanks
