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.
Late-Night Salivary Cortisol. Late-night salivary cortisol is one of the most sensitive diagnostic tests for Cushingâs syndrome. Elevated cortisol between 11:00 p.m. and midnight appears to be the earliest detectable abnormality in many patients with this disorder.hree diagnostic studies are currently recommended: late-night salivary cortisol, 24 hour urine free cortisol, low-dose dexamethasone suppression. If any of these tests is abnormal, a referral to an endocrinologist is strongly encouraged.
