Cortisol, Saliva
This test uses a saliva sample to measure a person’s Cortisol level. Saliva testing can provide just as accurate a measurement of adrenal hormones like Cortisol as a blood test can. Cortisol testing is usually ordered to aid in the diagnosis of conditions related to the adrenal and pituitary glands such as Addison's Disease, Cushing's Syndrome, Adrenocortical Insufficiency or Hypersecretion.
