ABO blood groups and HBs AG subtypes and titers in healthy carriers
The investigation covered 457 'healthy' HBsAg carriers detected following a screening by CEP. HBsAg in the sera of these subjects were subtyped by ID and titrated by CEP. The results obtained were analyzed according to the cases investigated. Differences were found between the distribution of blood groups among the normal unselected population and among 'healthy' carriers, where the incidence of AB subjects was much higher. The difference was more marked for the carriers of HBsAg/ad.
