> The neurosurgeon listening in (whom I was a neuro SHO with more years ago > than I care to remember) reply was "Give her a shot of steroids and MRI her > head urgently". Fine if you get the bloods off before giving the steroids. >> Robert Forrest > What steriods are given routinely in these cases - dexamethazone (which does not cross react in most cortisol assays) or cortisone? If dexamethazone had been given in the ER blood collected soon after would still be useful for cortisol analysis.
