I've perused on your blog "we never observe false-positive outcomes with the aggregate T4 test." Since you say "nearly," I'm pondering what, on the off chance that anything, may cause a false-positive outcome?

I have a 16-year old, male residential long hair feline who presently has an aggregate T4 estimation of 6.0 µg/dl (reference extend, 0.8-4.0 µg/dl) subsequent to being off of methimazole for 5 weeks. He has a long history of unending looseness of the bowels related with fiery entrail illness (IBD).

About a year back, we speculated hyperthyroidism dependent on a high-ordinary aggregate T4 with a high free T4 focus. He had thyroid scintigraphy around then to affirm hyperthyroidism and help with his radioiodine portion computation (we needed to guarantee that he wasn't overdosed — I would prefer not to wind up with a hypothyroid feline!). Shockingly, the aftereffects of this thyroid scintigraphy were negative (see his thyroid scintiscan above), however he was getting iodine supplements at the time.

Around a half year back, his serum T4 was somewhat higher (and his free T4 stayed high) so we began treatment with methimazole buy t4 liquid. He was on methimazole for around a half year, which lowered his T4, however the medication appeared to essentially compound his perpetual loose bowels, and he didn't put on any weight. My veterinarian has never possessed the capacity to palpate an extended thyroid tumor in my feline.

I am keen on I-131 treatment, however might want to be as sure as conceivable he is hyperthyroid before making courses of action. Could there be some other clarification for high aggregate and free T4 focuses Do you see false-positive outcomes?

His essential veterinarian and his internist both say they are aware of no other clarification for high aggregate T4 fixation other than hyperthyroidism. Be that as it may, when I read "never" on your blog, that appears to suggest it's conceivable (however improbable) to get a false-positive test outcome. Since I realize that you are the master on cat hyperthyroidism, I figured I would take a stab at requesting your recommendation buy t4 liquid. I would prefer not to seek after radioiodine treatment in the event that he isn't really hyperthyroid.
