Online vet, Dr. Marie

Dr. Marie replied:

Thanks for your question. It's unfortunate that your vet wasn't able to talk to you about the results! Hopefully I can help out.

When we do an ACTH stim test what we do is we measure a dog's cortisol level. Then, we give an injection of a medication that stimulates the adrenal glands. In a normal dog we will see the cortisol level go high. In a dog with Addison's disease, the cortisol level does not increase.

An initial cortisol level of 1 ug/dL is normal. When we stimulate it we expect it to increase to somewhere between 6 and 18. Therefore a level of 9 is quite normal.

So, judging by these numbers what we can say is that Bohdie does not have Addison's disease.

Of course though it's best to consult with your vet when he or she is available!
