Pet's info: Dog | Yorkshire Terrier | Male | neutered | 1 year and 4 months old | 14 lbs
My 6kg yorkie ate some grapes last Thursday. He took a blood test on Monday. The vet noticed that the SDMA were high within normal range, but thought the results were alright. When I look at them it seems like several things are quite high within normal range. This is a 1 year old dog... he shouldn't have elevated kidney results. Also ALT was very high but the vet wasn't worried about this either. I would love to have a 2nd opinion on these results. no vomiting, but he has been tired

How naughty of Hector to get into some grapes! It is extremely encouraging that his kidney values (particularly the creatinine and BUN) are within a normal range. The SDMA value is thought to be of use in detecting early signs of chronic kidney disease, but is not of much value when concerns about acute kidney disease arise (as in the case of grape ingestion). Remember that there is a wide range of normal to account for individual variation and values at the higher end of this normal range do not typically indicate a problem. I can see that Hector's ALT (a liver value) is mildly elevated, but in all honesty, I do not worry about elevations in this value until they are about twice the upper limits of normal (>240, whereas Hector's value is 181). That said, it is still worth asking your vet if it is possible simply to recheck this value in another week or two. It will most likely return to normal, but if it remains high or increases further, ongoing monitoring of the ALT and further diagnostic testing (bile acid testing, abdominal ultrasound, etc.) may be indicated. I hope this helps to clear up any confusion and that Hector continues to do well after eating grapes!
