Clinical Significance
Ethanol is the most commonly abused substance whose primary effect on the central nervous system varies with blood concentration. Not all individuals experience the same effects at a given blood level. Additionally, other central nervous system depressants can have an additive effect when taken in combination with ethanol. Approximately 5% of ethanol is excreted unchanged in urine. A positive urine ethanol result may suggest recent ethanol exposure and/or consumption; however, in diabetic patients with a urinary tract infection, ethanol is commonly present in urine as a result of glucose fermentation by yeast in the urine. When fermentation is not suspected, and urine ethanol is adjusted by a sample's creatinine concentration, urine ethanol may be used to estimate blood ethanol concentrations, as urine ethanol concentrations are approximately 130% of blood concentrations, if the patient is in the elimination phase. Caution should be exercised with interpretation of urine ethanol results; it is not recommended that a clinical decision be based solely on a urine ethanol result as there are several different scenarios that may have yielded the result.
