Nice numbers for Fritz. I hope you are all doing well. I think
@Marje and Gracie is out of town right now.
Yes you are correct that I was out of town but just got back

Thank you for tagging me!!
His albumin is likely high because of dehydration. That could be why the BUN is also a little higher but he’s been on a raw diet for a long time so the change from 20 to 41 makes me think “????” But it could still be a little dehydration in light of the elevated albumin. You could do a free catch urine sample and take it to the vet to check his urine specific gravity (they should have a refractometer in the office) and see what it is and if he’s concentrating his urine. The first urine of the morning is best to take over and it doesn’t need to be sterile. If you catch it before the vet is open, just put it in the fridge. If he’s not concentrating his urine, that indicates to me that he “might” be very early CKD. I say “might” because there can be other reasons for not concentrating the urine.
Like Karen, the CPK raises a concern to me. The CardioPet ProBNP is just that snapshot in time. It could be quite different today.
Glucose looks great as does his SS. What symptoms does he have that you think might be Cushings?
One suggestion I have is that because he’s over 10, every time you have labs done, ask for the senior panel. It will get you a complete superchem/cbc, urine, and tT4 for less that what you might have paid for the panels you got. I, personally, have full panels done on Tobey and Livia and they are still really young.
I hope you are well.....I’ve been hoping we could meet when you are down here in the winter sometime.
