Usually pancreatitis can be diagnosed with a Spec cPL.
If it is over 400, that is the diagnosis.
High lipase is a good indication of pancreatitis issues but it shouldn't be diagnosed by that alone.

A TLI can be done. A high level could indicate pancreatitis (although the Spec cPL is better for this). This test is sometimes done with vitamin B12 and folate level checks. Abnormalities in these could indicate intestinal disease.

In my opinion, she needs to be on a low fat food.
It is not a "wait and see if it happens again" thing.
I don't want to scare you but pancreatitis can be fatal.
It is quite dangerous and I would take every precaution that you feel is necessary.

Sometimes these dogs are sent home on Science Diet I/D and then they can be switched over to a store bought food. Some need to stay on the I/D. At teh very least I would look at the fat % in her food and then decide if you need to switch her.
