Inclusion criteria

Inclusion criteria: [Inclusion Criteria] 1. Participants who are enrolled in a study conducted at the Clinical Trial Center of Chungbuk National University Hospital in which alcohol consumption is scheduled, and who meet all inclusion and exclusion criteria of that parent study. 2. Participants who have received a detailed explanation regarding the evaluation of in-vivo changes and assessment of alcohol and its major metabolites following alcohol consumption, fully understand the study procedures, and voluntarily decide to participate by providing written informed consent.

Exclusion criteria

Exclusion criteria: [Exclusion Criteria] 1. Participants with a past or current medical history that makes blood sampling difficult, including but not limited to vasovagal syncope during venipuncture, anemia, or other conditions associated with intolerance to blood collection. 2. Participants who have donated whole blood within the past 2 months, donated blood components within the past 1 month, or received a blood transfusion within the past 1 month prior to blood sampling. 3. Participants who are deemed inappropriate for study participation by the investigator due to medical history or other reasons, including underlying conditions that may interfere with safe participation in the study.
