Just high BUN and high CREA

vet test
BUN 38mg/dL High (16 -36. )
CREA 2.7 mg/dL HIGH (0.8 -2.4 )
I don't know what this really means but just showing you guys.
I can't say for sure on any results from a urinalysis as I don't run those at work.

But the Serum tests I do run at work.

The BUN and CREATININE are above normal levels but not by alot, and those ranges can vary depending on the machine or particular lab that runs them. On our machine a CREAT of above 2.0 is considered above normal, apparently on your vets machine 2.4 is considered within normal range.

Based on their ranges and the results it appears the levels are elevated some. They would actually need lab work prior to the cat getting sick to determine if those are normal levels for that particular cat or if in fact they are elevated. Or doing a repeat of the BUN and CREAT in a week or two and see if the levels continue to go up, stay the same or go into the 'normal' range. Is your vet giving IV fluids to your cat?

Just for reference; in very seriously ill cats at work we've seen BUN levels in the 70-80 range, and CREAT levels in the 4-7 range and some even higher.

Dusty had lab work done a few years ago and had a CREAT level of 2.4 (by our machine that was above normal. I had been feeding her "light" food which does not come in a senior fomula only adult. So I switched her back to a senior food and a few weeks later we retested and her CREAT level came back down to 1.8 (which is normal). All that from only a minor change in food from adult to senior.

Many things can affect those levels from food, to stress, to illness.
