Dog and Cushing's (Hyperadrenocorticism)

If the cortisol:creatinine test comes back normal, then it is unlikely that Cushing's is present, and we do not routinely recommend the following screening tests. A cortisol:creatinine ratio test that is high means Cushing's might be present, and needs one of the other screening tests to determine if Cushing's is indeed present.
