Open Access Abstract Introduction Adrenal failure AF is associated with increased mortality in septic patients. Nonetheless there is no agreement regarding the best diagnostic criteria for AF. We compared the diagnosis of AF considering different baseline total cortisol cutoff values and Amax values after low 1 pg and high 249 pg doses of corticotropin we analyzed the impact of serum albumin on AF identification and we correlated laboratorial AF with norepinephrine removal. Methods A prospective noninterventional study was performed in an intensive care unit from May 2002 to May 2005 including septic shock patients over 18 years old without previous steroid usage. After measurement of serum albumin and baseline total cortisol the patients were sequentially submitted to 1 pg and 249 pg corticotropin tests with a 60-minute interval between doses. Post-stimuli cortisol levels were drawn 60 minutes after each test cortisol 60 and cortisol
