You are in a danger zone.
Borucki et al., 2005. In this study, 17 test subjects were dosed with measured drinks (equivalent of 8 drinks) in a hospital setting. For each test subject, the levels of four biomarkers (including EtG) were tested eight times over a 102-h period after drinking. This study used measured alcohol doses and a positive cut-off of 100 ng/ml. [The difference in this test is time was calculated from final drink and not 0-BAC] In the first 24 h after drinking, all EtG tests were positive. After 54.3 h, 77% of the test results were positive; while after 78.5 h, only 18% of the test results were positive. As you can see the results vary from one individual to another. This wide interindividual variation is characteristic of all the EtG elimination studies to date.
I were to estimate, on average, your EtG clearance should be in the range of 60-72 hours based on volume consumed But it is possible that it could be as little as 48 hours.
