  2. Study First Submitted
  • Stopped: an ongoing trial was terminated, suspended or withdrawn.
  • Notable: the trial’s plan changed such as a big move in its timeline or size, a new primary endpoint, sponsor or phase, or recruiting opened or resumed.
  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
The goal of this observational study is to determine whether a clinically relevant dose of activated charcoal raises the serum osmolality and osmolal gap in a population of healthy volunteers. Secondarily to determine whether the same dose creates a false positive result using an enzymatic assay. 1. Does a clinically relevant dose of commercially available activated charcoal raise the osmolal gap above the baseline of a healthy volunteer? 2. Does the same dose of charcoal cause a false positive enzymatic assay for ethylene glycol? Participants will be asked to consume a dose of activated charcoal and have serial blood draws for laboratory measurements.
