But I will get a copy when we go to the vet tomorrow. I will post the numbers then. The vet is stumped by the low blood platelets and low WBC. He did say the blood in the urine could be caused from low WBC, but he doesn't know what would be causing excess protein in urine. Maybe we will be getting some answers tomorrow. What is involved in treating a cat with CRF. We lost our soulmate Max several years ago to acute kidney failure. That was a real bummer.

Well high Creat and high BUN would signify kidney issues (this should be a no-brainer to a Vet, no offense).
You mentioned blood in urine in your 2nd post but not your first. Blood is a protein so if there's blood in the urine, the urine will show high for protein (again, a vet should know this). Plus if there's blood in the urine, hopefully your Vet will be considering a urinary tract infection, doing a urinalysis and treating with antibiotics. In cats with CRF, their urine is much more dilute (as their kidneys have lost the ability to concentrate their urine). Long story short, they're more at risk for UTIs (urinary tract infections). Did the Vet put kitty on antibiotic for a UTI?
Low platelets in a cat is not unusual............often platelets "clump" so when the machine analyzes the blood, it gives the impression of very low platelets only because the platelets are "stuck together." Most of my cats' bloodwork has shown low platelets due to 'clumping.' I keep copies of all of my cats' bloodwork, for years now....and I can't tell you how many times the results will show low platelets (very low) and often the tech who runs the machine that analyzes the blood will make a note beside the low platelet result "clumping". It's very common, so that's something your vet should surely consider.
Low WBC count generally signifies a viral infection.
Have you considered a second opinion from another Vet? With all due respect if your vet is so "stumped" by these results, well, I'm a little stumped with your Vet. Again, no offense.
Also........cats with CRF generally have a fair bit of protein in the urine as well (again, a Vet should know this).
EDIT: Oops, I re-read your original post and see you mentioned that Vet started cat on Clavamox for blood in urine (obviously he believes same is a UTI).
ALSO - did your Vet run what they call a "differential"? Generally when they do a CBC on a cat (complete bloodcell count, which includes WBC, RBC, platelets, Hemacrit, hemoglobin), they'll also further analyze some of the components of the WBCs.....neutrophils, basophils, lymphocytes, etc. Depending on the results of these, they can help tell more of the story about what might be going on.
Here's a good website that explains in more depth, about lab tests in animals, namely White Blood Cells and the various components of WBCs.....and note the following:

The above is from this page......scroll down to the section on White Blood Cells:
http://www.peteducation.com/article....2+1473&aid=987
You can read there about the other components of WBCs; neutrophils, basophils, monocytes, lymphocytes, eosinophils................so what your Vet needs to do is look at the results for these, because each one of these make up WBCs and elevations or increases in each of these 5 can help to shed light on the overall status of the elevated or decreased WBCs.
Some clinics just do a very basic CBC which doesn't do a 'differential of the WBCs', that specifically analyzes the above 5 components.......I know one clinic I went to, if they needed to just have the basics (WBC, RBC, platelets, hemoglobin), they'd do what's called a "QBC"....which means "quick blood count"........but a proper CBC (or a full one) includes analyzes the WBCs. Ask your Vet if the bloodwork he did included a "differential" of the WBCs........if he doesn't know what "differential" means........ask him if the labwork he did analyzes the various components of the WBCs; neutrophils, lymphocytes, basophils, etc. If not, request this be done. If he does bloodwork in his clinic "in house" and can't do this, ask him to collect another sample from your kitty and send it off to the nearest Vet Lab for a full analysis. You as an owner have a right to make this request and it's not the least bit out of line.
Did he give your kitty any subcutaneous fluids? With elevated BUN and Creat, kitty is likely dehydrated and should have some fluids for sure (or is kitty still there at the Vet and on an IV?)
Just so you know.............I've had 5 cats for many, many years.......some younger, some older. There have been a few times where one of my cats' will have bloodwork and it will be noted that their WBC count is low. I remember being upset about it, worried.....but then the next time they had bloodwork, it was normal.
