What does a positive ethyl glucuronide test mean?
A positive interpretation will be given if either the ethyl glucuronide (EtG) result is greater than or equal to 250 ng/mL and/or the ethyl sulfate (EtS) is greater than or equal to 100 ng/mL. A “high” positive (ie, >1000 ng/mL) may indicate: -Heavy drinking on the same day or previously (ie, previous day or 2).
What is a low EtG level?
A “low” positive EtG test (for example, 500 to 1,000ng/mL) may indicate: Heavy drinking within the last one to three days. Light drinking within the last 24 hours. Recent intense exposure to environmental products containing alcohol (within the last 24 hours)7
What can cause false positive EtG?
False positive and false negative results have been reported with both EtG and EtS. False positive test results may be due to incidental exposure to alcohol-containing products such as mouthwash and hand sanitizers, especially if a lower cutoff concentration is used.
How far back can an EtG test detect alcohol?
Why is Urine EtG Detection Any Better than a Blood or Breath Alcohol Test? EtG can be found in the urine much longer than alcohol in the blood or breath. After a few drinks, EtG can be present in the urine up to 48 hours, and sometimes up to 72 or hours or longer if the drinking is heavier.
Can hand sanitizer show up in a urine test?
Frequent use of alcohol-containing hand sanitizer won’t get you drunk, but it may lead you to test positive in a urine test for alcohol consumption, according to a recent study.
How long does EtG peak?
Two primary factors to determine the window of detection is based on volume of alcohol consumed and the time between each drink. A person that consumes 3 drinks can only have a detectable level of EtG for approximately 20 to 24 hours. The level peaks at approximately 9 hours with an EtG level around 15,000 ng/mL.
Can you pass an EtG test in 36 hours?
Some studies show EtG is detectible from 24 to 120 hours after the alcohol is processed, but others say between 24 and 72 hours, all depending on the amount of alcohol that entered your body.
