Anti-HBs antibody concentrations in serum were measured by CLIA Assay. Concentrations were presented as geometric mean concentrations, in milli-International Units per milliliter (mIU/mL). Analysis was initially planned to be performed by Enzyme-Linked Immunosorbent Assay (ELISA). A decrease in the specificity of the anti-HB ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL). Following these laboratory quality issues, GSB Biologicals decided to stop testing with the HBs in-house ELISA and to have the anti-HB analysis performed using the new validated CLIA assay. This outcome measure concerns solely subjects part of the HLA Subsets 1 & 2 who received the Day 360 booster dose of HBsAg.
