Alcohol use screening in pregnancy with a questionnaire and a blood test

Official title: Evaluation of the Diagnostic Value of the Self-report T-ACE for Screening of High-risk Alcohol Consumption During Pregnancy : Comparison With the Dosage of a Blood Biomarker Used as Gold Standard. AUTOQUEST Study.

Run by University Hospital, Lille · NCT04786587 · Data updated 2026-11-12

This project will test whether a short self-report questionnaire (T-ACE) can reliably detect high alcohol use in pregnant women by comparing answers with a blood biomarker (phosphatidylethanol).

Is this trial a fit for you?

Likely a good fit

Adult pregnant women (18+) receiving prenatal care at one of the three participating maternity hospitals in northern France who return the self-report and give written consent are eligible.

Probably not a fit

Women under 18, those not pregnant, those who do not return the self-report or who refuse consent will not participate and therefore will not receive any direct benefit from this study.

What this trial studies

This is a multicenter prospective diagnostic study enrolling 2,425 pregnant women at three maternity hospitals in northern France. Participants complete a self-administered T-ACE questionnaire during a prenatal visit and are offered a single blood test for phosphatidylethanol (PEth). The study compares questionnaire results against the PEth biomarker to determine how well the T-ACE identifies high-risk alcohol consumption during pregnancy. Inclusion requires age 18 or older, returned self-report, and written consent.

Why it matters

Potential benefit: If successful, this could give clinics a simple questionnaire to identify pregnant women who drink heavily so they can be offered earlier support or interventions.

How similar studies have gone: T-ACE is widely used in pregnancy but its diagnostic accuracy against biomarkers like PEth is not well established, and prior biomarker comparisons have produced mixed results.
