title: Relationship of subtypes of hepatitis B surface antigen with e antigen and its corresponding antibody.
abstract: A total of 3,212 samples of blood from asymptomatic volunteer donors positive for hepatitis B surface antigen (HBsAg) by radioimmunoassay and 860 samples negative for HBsAg were tested for the presence of hepatitis e antigen (HBeAg) and its corresponding antibody (anti-HBe) using a rheophoresis technique. Neither HBeAg nor anti-HBe was detected in any sample negative for HBsAg. Of the HBsAg-positive samples, 237 (7.4%) contained HBeAg and 749 (23.3%) had anti-HBe. HBeAg was significantly (P less than or equal to 0.0005) more likely to be in samples with high titers of HBsAg. Anti-HBe had an equal chance of occurring in samples with low or high titers of HBsAg. Both HBeAg and anti-HBe were found in samples with HBsAg subtypes ad or ay. However, a significant association (P less than or equal to 0.0005) between HBsAg/ay and HBeAg as well as an association between anti-HBe and HBsAg/ad was found.
