Pet's info: Dog | Chihuahua | Female | spayed | 1 year and 2 months old | 14 lbs
Hello. My 1 year old dog just got her lab work back and her ALT/SGPT (ALT) was elevated, at 137, when the normal range is 10.000 - 100.000 U/L. When tested 9 months ago her level was only at 32. She is going back in a couple weeks for a re-test and follow up, and I was just nervous about what could cause that number to be so high. Is that considered very high, or just a little high? She wasn't fasting for this blood test. I hope it's curable if it is something. Any advice is appreciated!

There are many reasons that Ellie could have an elevated ALT value. This liver enzyme is very reactive and common benign causes of elevation include jostling of the liver (like missing a jump and hitting the upper abdominal area instead), or a small amount of bacteria getting in the blood stream and being processed by the liver. It can indicate more significant problems like toxin ingestion or the beginning stages of liver disease. The elevation at this point is considered minor but it is important to monitor her closely for any signs of lethargy, vomiting, diarrhea or decreased appetite as these could indicate a progression of things. There is a supplement called Denamarin that can help the liver when it is having elevated enzymes. Most commonly, the reason is benign. Make sure to follow up with the blood work to identify the trend. I hope this helps!
