Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Bloodwork can be diagnostic. It can diagnose: diabetes, kidney failure, liver disease, thyroid conditions, it can make you suspicious for cancer, leukemia’s, immune conditions if anemic or low platelets, blood parasites, tick borne disease, some viral feline diseases. Sometimes the blood work does come back perfectly normal which rules out a lot of things but doesn’t give a diagnosis. Which then prompts further testing or diagnostics to try to get an answer. I’m not sure what is wrong with your pet. But we are here to help if you need us. I hope this helps!
