Summary
This study looks at whether taking activated charcoal can change certain blood test results, like osmolality and ethylene glycol levels. Eight healthy volunteers will take a dose of charcoal and have blood drawn over six hours. The goal is to see if charcoal causes false positives or altered readings, which could affect how doctors diagnose poisoning.
