An individual with a blood alcohol content level of .08 will have no measurable alcohol in the bloodstream roughly 5.33 hours after the last drink (.08 divided by .015 = 5.33). With some urine alcohol tests, alcohol can be detected up to approximately 48 hours after an individual has consumed alcohol.
EtG has become a reliable indicator of alcohol consumption as the metabolite can be found in urine for up to five days after drinking.he test has been challenged when low levels of EtG are found in urine. Whether a regular or occasional drinker, testing requirements may ask for higher cutoff levels of the metabolite (perhaps 500 ng/ml as opposed to 100) to get around claims of incidental exposure versus drinking outright.
