Hi,
The reference range is incorrect for a dog on Trilostane (Vetoryl). The range for these pups is 1.45 to 5.4 ug/dl and can go up to 9.1 ug/dl if all signs are under control. The post number of 1.8 ug/dl is getting down there so keep an eye on her for any signs that her cortisol is lower than is comfortable for her.
The optimal time to test a pup on Vetoryl is 4-6 hours after the last dose and the dog should NOT be fasted.
Keep up the good work!
Hugs,
Leslie and the gang
