Because underreporting can occur, abstinence biomarkers are necessary during hepatology outpatient service. This study assesses whether serial changes of the serum carbohydrate\u2010deficient transferrin to transferrin ratio (%CDT) reflect patient abstinence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively investigated serial %CDT measurements and laboratory data from two outpatient settings: patients in an alcohol rehabilitation program (A), and ALD patients at a hepatology clinic (H) who attempted abstinence with self\u2010diary monitoring. Using group A data, correlation coefficients were determined between the number of days from the last drink (abstinence days) and laboratory data. Linear approximation was applied for significant coefficients. Using these results, %CDT was validated for group H.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Group A data were 223 data samples from 55 cases with abstinence days. Four (7%) were diagnosed as having cirrhosis. Eighteen patients continued abstinence over 30\u2009days. %CDT (<jats:italic>Rho<\/jats:italic>\u2009=\u2009\u22120.50, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and GGT (<jats:italic>Rho<\/jats:italic>\u2009=\u2009\u22120.34, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01) were negatively correlated with abstinence days. For %CDT, negative linear approximation was maintained with the number of days (<jats:italic>y<\/jats:italic>\u2009=\u20092.01\u20130.004 <jats:italic>x<\/jats:italic>).<\/jats:p><jats:p>Group H data were 18 cases, of which 12 (66%) were diagnosed as cirrhosis cases. Seven patients reported continued abstinence for 8\u2009weeks, during which time %CDT values dropped significantly. The group H %CDT was higher than the group A %CDT, perhaps because of severer liver disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The %CDT trend assessment is useful to support continued, multi\u2010month self\u2010reported abstinence from alcohol, but it must be interpreted carefully in severe liver disorder
