Refer to Platinium profile (TP5) for advised complete thyroid panel including TT4. Thirteen TGA‐positive canine categorized as hypothyroid based mostly on subnormal FT4 concentrations by ED.
- Hypothyroid canines may have a TSH stage above the reference interval in about two-thirds of instances.
- In most sufferers, follow-up of TSH does not provide a major advantage over a measurement of T4 solely.
- On the other hand, the consequences of non-thyroidal sickness on TT4 means that many canine with regular thyroid operate may also have a low TT4 making the check poorly specific.
- For dogs that present with scientific signs as the end result of a raw fed diet, a change of their meals may resolve the signs.
