what blood results means

First of all hi to everybody. I hv one question. I hv 6years old female greyhound. Ex racer. Raw feed. We have just done complete blood works and my vet is concerned about some values:
BUN: 38 and Crea: 2.2. He said that all other values are normal.
He said that there is some kidney problem. As she is a greyhound and raw feed i know some values can be higher than "normal". But how high?
The blood was taken 12hours after she had her last meal and 10 hours since she drunk water. she is also on cyclosporine and i've been told that this medication can increase creatine levels.
Are this values saying that something is wrong with her kidney? Thank you so much for your answer. D.

Hi D. That is such great news. You must be so relieved. I'm delighted for you and it brought a smile to my face this morning. More often than not, the news we get here is sad, so it's great to get some truly wonderful news.

Give Greta a huge hug from me.

Hi Tony! I can see from the photo that BB was special. She look very smart and just waiting to read your needs to please them. They are so incedible. I'm really sorry for your loss. Greta is my first dog so i con not know the pain you feel, but i can imagine.

But!...my vet had great news for me today (and you ;-) ). We did urinanalysis today and all values come back normal. Ow..yeah...

Seems (as you said) that her normal creatinine level is 2,1 or 2,2 and the BUN was high just because of dehydration.

Well I will still keep the change of vegetables as seems she enjoy them.

Tony thank you again. Please keep doing what are you doing. I'm sure BB is always beside you. D.

Hi D. You are very kind. Thank you for your generous comments. Yes, BB was a very special dog, my companion for 12 years and my world changed when she passed away. I still miss her. Please let me know the results of the urinalysis. I'm hoping the results are negative for protein leakage, but it's a worthwhile test to be certain. The other point being, if it is the early beginnings of kidney disease, there is a lot you can do to treat and manage it at this stage.

Hope you have a nice day too.

Good morning, Ok then. Now the things are clear. I think everythink is ok with her. However, we will do urinanalysis and i will add vegs to her diet. She already has different animal protein as chichen, turkey, pork, beef, venson, fish etc.etc.. I'm sure her BUN was increased because of raw food and because she was not drinking for 10 hours before blood tests. She drinks about 1,6l to max 2l of water a day and that is ok i think.
Tony thank you to be here and help us with our fur companions.
B.T:W I read your story and i read about BB on you page.Beautiful dog. In name of her you are doing amazing job for other pets. I''m sure you saved a lot of them.
Have a great day and thank you again. D.

Hi. Yes, just raw meat as the diet can affect the values. I think you need to devise a varied diet, including the raw meat, if that's what she's used to. So, canine friendly vegetables, white fish, chicken, are all good for dogs. I wouldn't give raw chicken or raw fish though, due to the potential for salmonella, bacteria and other problems.

Yes, dehydration will always increase the BUN level.

Thank you Tony for your replay. I have blood values from before she was raw feed and before she was daily on Cyclosporine due her Pannus. Crea was 2.1 and BUN was 29.  My vet's opinion is that the values are so high sice i feed only animal protein and not vegs. I realy don't think that vegs are not good i only think that dogs don't need them. Thats only my opinion. So i can feed vegs but my question is will this realy make values of crea and bun lower and becouse the kidney are overloded becouse of animal proteins?
And is posible that bun was elevated becouse of dehidration?
Well i will do as you suggest. We will do also urinanalysis. Thank you so much for your opinion. It means a lot to me as another vet was teating my dog's kidney disease with AB when there was no disease. That time i didn't know about different blood values of greyhounds.

Not unusual for me ... I closed before finishing ... sorry. BUN can also be higher (as a normal value for greyhounds), but mainly in female greyhounds rather than males. This can also be elevated due to raw feed too, so one way or another, your greyhound may very well have absolutely normal values - for her. It is definitely a worthwhile process to get the urinalysis done, I would say sooner rather than later.

Hi ... and welcome to our family of friends here. I own a greyhound (rescued), so I know how it can be confusing sometimes. Their values are sometimes higher than normal, particularly creatinine, due to their extreme muscle mass tissue.

The creatinine could actually be normal (for your greyhound), as it isn't extremely high. Does your vet have a previous record of values that he can compare this reading with? If not, do you remember the last vet she saw - if you got her from a rescue centre, they may have some blood readings on file at the vet they use.

BUN is higher than normal, so it may be there is something going on. I would strongly advise your vet does a urinalysis and looks for protein leakage. If there are proteins in the urine, then kidney disease is more likely.

I wrote a list of blood values and how they are interpreted, which you may find useful. You can access that document through MedHelp:

Hope that helps.
