Anonymized serum specimens scheduled for destruction following medical testing were collected between April 2013 and April 2014 from individuals granting consent. Specimens were tested for HBV antibodies, surface antigen (HBsAg), and HBV DNA to perform molecular characterization. Four thousand eight hundred and two specimens (13% of the population) were collected, with a resulting median age of 29years (range 1week to 93years).
