My tattoos were rarely itchy, either. My favorite carrier oils to use have been avocado oil, sweet almond oil, and emu oil. My favorite essential oils for my tattoo healing have been frankincense, lavender, helichrysum, and myrrh.
Further Tests. There are other tests used for the diagnosis of Cushingâs disease such as the dexamethasone suppression and corticotropin-releasing hormone (CRH) stimulation tests. However, these are not as reliable in distinguishing between the causes as IPSS. A doctor may want to do multiple tests to confirm the results.
Dexamethasone suppression test. The dexamethasone suppression test (DST) is used to assess adrenal gland function by measuring how cortisol levels change in response to an injection of dexamethasone. It is typically used to diagnose Cushing's syndrome.
