I can ask my vet I guess. Although she does most of her own lab work. When I mentioned sending a DNA blood sample to Avian Biotech though for Pete she told me they don't use that lab anymore because there were too many mistakes. I didn't ask what kind of mistakes though or how long ago that happened.
I think some lab once made a mistake with my bloodwork though. I had one test come back positive for rheumatoid factor (RA), but all the rest of the results were different as well as what I have always had. Then they ran the tests again and they came back all the same as they had for 10 years. So honestly, I think they sent my doctor someone else's test results!
