Blood xenobiotic Elevated blood ethylene glycol concentration 2024-03-17T14:37:46Z Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents including antifreeze. Exposures are generally observed due to accidental or intentional ingestions, with its sweet taste lending to accidental toxic exposures, whereas intentional exposures may be motivated by a suicide attempt or desire for inebriation in the absence of ethanol. The concentration of ethylene glycol in the blood is above the upper limit of a guidance value for total concentrations that implies possible injurious effects.
