Don't mean to hijack this thread, but sometimes doing the tests doesn't help, either. I thought for sure that we would get a clear picture as the input above would suggest. Had the full panel run on Suze thru Idexx:
Thyroid Panel #4 - Free T4: FreeT4 (ng/dL) is 0.7 - ref. Range 0.6 - 3.7.
Free T4 (pmoll/L) is 9.0, ref Range 7.7 - 47.6.
Thyroid Panel #4 - T4: T4 is .7, Ref Range 1.5 = 4.0 ug/dl.
Thyroid Panel #4 - cTSH: TSH is .68 - Ref. Range 0.05 - 0.42
This dog (7-1/2 years old) is incontinent, high cholesterol, high blood pressure (230 - 260 a week ago), is hot all the time, listless, depressed and has symptoms of Von Willebrand disease - still waiting on those results. All other Super Chem 27 and CBC results are within normal range. PCR was done for Lyme, Babesia, Anaplasma SPP, Ehrlichia, RMSF, Hepatozoon SPP, Leishmania, Neorickettsia and Bartonella - all negative.
If the Von Willebrand comes back negative, a cystocentisis will be done for a UA, UPC and a culture.
Why would the TSH be so high? Would you treat a dog with these symptoms?
