Brief Summary: This paper describes a novel ambulatory fraction collector that can be used with microdialysis to obtain high resolution steroid profiles over a 24-hour period.Comment: The natural circadian and ultradian secretion of adrenal hormones makes single timepoint measurements of these hormones uninformative for clinical decision making (1-3). Repeated sampling during the day requires admission into an atypical, and often disruptive, clinical set...
