OK suspected something was off with my dog so I did a thyroid test at a clinic and just got back the results. Any info or help is very appreciated.

T3(ria) = 73 normal range 45-150
T4 = 1.4 normal range 0.8-3.5
Free T3 = 0.8 Normal range 1.7-5.3
Free T4(equilibrium dialysis) = 30.3 normal range 8-40
T3AA = 0.8 normal is less than 2.0
T4AA = 0.9 normal is less than 2.0
TSH = 0.10 normal range 0.0-0.60
TGAA = 1%

So Free T3 is well below normal is that a cause for concern? Does reverse T3 show up in dogs or only humans? Spayed 7 year old bitch not on any meds, no vaccines in past 6 months.

Also tested my other dog and got high results for T3AA and T4AA

T3=73
T4= 1.3
FreeT3= 3.3
FreeT4= 27.9
T3AA= 3.3
T4AA=2.0
TSH = 0.05

TGAA to be done.

Is your dog currently on any meds or vaccinated within the last 30 days? Some think factors such as these will produce abnormal readings.

Dodds website has some good reading.

This panel was mostly likely done at Michigan State University. When they do a thyroid panel, you should get an interpretation that basically answers those questions. The vet submitting the panel has to check the box requesting the interpretation. If they did not, please ask them to call and request one. The endocrinologists at Michigan will look at all the results, check to see if your dog is on meds or has any other clinical diseases and tell you what the panel results mean.
