How accurate is EtG urine test?
The EtG test is quite sensitive and can detect even low levels of alcohol.
In fact, the test can detect alcohol in the urine up to five days after consumption.
In studies of participants without alcohol-use disorders, EtG has been detected in urine samples for up to 80 hours (3.3 days) after heavy alcohol exposure..
How long can EtS be detected in urine?
While most of these excretory products are detectable in urine for very short periods of time (less than 24 hours), ethyl glucuronide (EtG) and ethyl sulfate (EtS) have longer half-lives and may be detectable in urine for up to 96 hours, depending on the dose taken prior to specimen collection.
Is EtG test really 80 hours?
Although EtG and EtS testing has been widely marketed as an “80 hour test”, current studies suggest that this may not apply to all amounts of alcohol exposure.
Can EtG be detected after 120 hours?
Sensitivity and Specificity Overall, the EtG immunoassay was able to correctly identify self-reported drinking from 24 (AUC=0.90, 95% CI: 0.88, 0.92) to 120 hours (AUC=0.88, 95% CI: 0.87, 0.90).
How quickly does EtG leave the body?
How Does An EtG Urine Test Work? Ethyl Glucuronide (EtG) is a metabolite of ethyl alcohol. The body breaks alcohol down into different metabolites, one of them is EtG. EtG remains present in the body for about one to five days after drinking, depending on how much alcohol a person consumes.
Will I pass an EtG after 48 hours?
Conclusions. Any drinking the night before should be detectable the following morning with EtG cutoffs of 100 or 200 ng/mL. Twenty-four hours after drinking, sensitivity is poor for light drinking, but good for heavier consumption. At 48 hours, sensitivity is low following 6 drinks or less.
