Using quantitative maternal surface antigen (HBsAg) to predict HBV infection in infants has not been investigated. We enrolled 526 mother\u2010infant pairs with positive maternal HBsAg under current immunoprophylaxis. Maternal viral load and quantitative HBsAg were measured in the peripartum period. Infant HBsAg seropositivity for more than 6 months was defined as chronic infection. Rates of chronic infection in infants at various maternal HBsAg levels were estimated using a multivariate logistic regression model. Results showed that maternal HBsAg was positively correlated with maternal viral load (r = 0.69; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001) and accurately predicted maternal viral load above 6, 7, and 8 log<jats:sub>10<\/jats:sub> IU\/mL with an area under the receiver operating characteristic curve (AUC) of 0.97, 0.98, and 0.95. Nineteen infants were chronically infected. After adjustment for the other risk factor, maternal HBsAg level was significantly associated with risk of infection (adjusted odds ratio for each log<jats:sub>10<\/jats:sub> IU\/mL increase, 15.02; 95% confidence interval [CI], 3.89\u201057.94; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001). The AUC for predicting infection by quantitative maternal HBsAg was comparable to that by maternal viral load (0.89 vs. 0.87; <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.459). Estimated rates of infection at maternal HBsAg levels of 4, 4.5, and 5 log<jats:sub>10<\/jats:sub> IU\/mL were 2.4% (95% CI, 0.1\u20104.6; <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.04), 8.6% (95% CI, 4.5\u201012.7; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001), and 26.4% (95% CI, 12.6\u201040.2; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001). <jats:italic toggle=\"yes\">Conclusion:<\/jats:italic> Quantitative maternal HBsAg predicts infection in infants as well as maternal viral load does.
