^aOnboard dilution for Elecsys 2010 or cobas e 411 (*) and Modular Analytics E170, cobas e 601, or cobas e 602 (†), respectively. The mandatory dilution algorithm incorporating onboard dilution eliminates any potential high-dose hook effect. >130‡ indicates that the HBsAg level in the diluted sample is above the upper limit of detection for the assay; therefore, the level in the undiluted sample cannot be calculated. <0.05# indicates that the HBsAg level in the diluted sample is below the lower limit of detection for the assay; therefore, the level in the undiluted sample cannot be calculated.
