  • When Cushing syndrome is considered, several variations in the diagnostic workup, when compared to that for nonpregnant women, may be necessary.[emedicine.medscape.com]
Cortisol Increased
  • We then draw blood from the IV to see if the levels of growth hormone or cortisol increase as we would expect.[chw.org]
  • The increase in total serum cortisol is partly due to an increase in cortisol-binding globulin, but the unbound or free cortisol increases as well.[emedicine.medscape.com]
