  • Use:
    Detect significant levels of ethylene glycol in blood
  • Clinical Significance:
    Ethylene Glycol (EG) is the primary component of many antifreeze solutions. Given its physical properties, EG may be considered a derivative of ethyl alcohol (drinking alcohol). The inebriating effects of EG may account for its occasional use as an intoxicating beverage.EG ingestion is a relatively infrequent, but important, cause of acute clinical intoxication. It is estimated that 40﷓60 people die per year due to EG poisoning. The ingestion of EG may result in severe central nervous system depression, cardiopulmonary failure, acute renal failure, severe metabolic acidosis and death.
