Phosphatidylethanol and Other Ethanol Consumption Markers
Recruiting now · Not applicable
Conditions studied: Healthy Volunteer, Alcohol Consumption
In brief
This study is intended to help the investigators understand how a biomarker found in the blood may be used to better identify the quantity and different patterns of alcohol use. The investigators hope that the results of this study will help identify the uses of alcohol-use markers in the blood in future alcohol prevention and treatment programs. It is hoped that the information learned from this study will benefit other people in the future. The study participants will come into the lab and will (1) consume alcohol in the lab designed to produce a peak blood alcohol concentration of 0.06% and have blood collected over 6 hours followed by abstinence for 10 days to give a small blood sample 4 times and (2) to give a small amount of blood 5 times within 28 days (naturalistic drinking) and provide answers about alcohol use.
