Actually this was the second one I had done. The first was near the beginning of the year and Tuxie was not having an episode at that time. I thought because it was done non-fasting rather than fasting that is usually required, that it may have been falsely high. Tuxie had no signs of pancreatitis...no inappetance, no weight loss, no vomiting, no lethargy, ate well and acted basically normal. I chose to have the first one done since the U/S had shown orgamomegaly...inflammed pancreas, kidneys and adrenals and his glucose numbers were not even close to regulated. The second fPLI test I had done was just a few days ago at the time of a minor episode with vomitting and inappetance, which subsided with one 200ml Sub Q fluid and one shot of cerenia.
His lack of symptoms is very confusing for me and both vets at the clinic I deal with. I had the Feline TLI done (Gastrointestinal Function Lab, Texas) at the same time as the second specific fPLI and it came back very high 482 with reference range of 12-82. This again is indicitive of pancreatitis.
I am having a LDDS test done to rule out Cushing's before I decide to start the steroid treatment. The vet who did the U/S said the results were consisitent with Cushing's. I did have an oral HDDS test done and it came back as negative, but the LDDS test is supposed to be more accurate.
