Thanks for this question. Actually a PETH test looks back at your alcohol usage over the last 3-4 weeks. It checks the blood for direct byproducts produced by consumption of alcohol namely phosphatidylethanol. These byproducts can remain in your system for upto 3 weeks or longer in some cases. It is thought this is the most accurate test to determine whether a person has been using alcohol and can also estimate the amount of alcohol that person has used. Now usually a level of greater than 95 ng/ml indicates that a person has had 2 binge sessions per day over the last three weeks. A level of 700 ng/ml is EXTREMELY high and this would mean that the person whose test was done has had multiple binge drinking sessions per day over the last three weeks.

Do you have any more questions?
