Kurz nach einer Hepatitis-B-Impfung kann der Test falsch positiv sein, da HBsAg als Impfstoff verwendet wird. WebHBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious). HBeAg is considered a marker for cccDNA replication. [1] thin line synonym
