568 HBsAg carriers were subjected to liver biopsy. The specimens were fixed in formalin and the δ antigen was detected by immunofluorescence. Some patients also made frozen sections of liver specimens, the same specimen fixed and frozen sections were detected in liver δ antigen, which is still testing the intrahepatic HBcAg. Results Of the 568 HBsAg carriers, 137 (111, 26) had positive intrahepatic δ antigen, with the highest positive rate in 21-40 years old.
