Is etg 500 ng/ml, ets 100 ng/ml considered a high cutoff level? what is the lowest and highest cutoffs for etg/ets? thanks

These are the most: frequently used cut off levels, according to my brief research. These cutoffs, it is reported, minimize the possibility of a positive being due to "incidental" exposure. A positive test would typically be confirmed with a follow-up test. Any positive result means the liver has processed alcohol. In general, the greater the ng/mL value, the more recent and/or heavy consumption has been. Stay well:)
