Cortisol Blood Test, LC-MS
The cortisol blood test is used to help diagnose Cushing syndrome or primary or secondary adrenal insufficiency (Addison disease); to detect conditions affecting the pituitary or adrenal glands.
Second-order testing when cortisol measurement by immunoassay (eg, CORT / Cortisol, Serum) gives results that are not consistent with clinical symptoms, or if patients are known to, or suspected of, taking exogenous synthetic steroids. For confirming the presence of synthetic steroids, order SGSS / Synthetic Glucocorticoid Screen, Serum.
