ASCP Technologist in Immunology (I) Practice Exam

HBeAg positivity in the context of hepatitis B is an important marker for assessing the infectivity of an individual infected with the hepatitis B virus (HBV). When HBeAg is present in the blood, it indicates that the virus is replicating actively, suggesting that the person is highly infectious.

The presence of HBeAg correlates with a high level of viral replication, which means that the infected individual has a greater risk of transmitting the virus to others through bodily fluids. This is particularly relevant in clinical settings, as HBeAg status can help inform decisions about patient management, including the need for antiviral therapy and precautions to prevent transmission.

In contrast, the other options do not accurately reflect the implications of HBeAg positivity. Low infectious status would indicate lower levels of HBV replication and a reduced risk of transmission, which is not the case with HBeAg positivity. Recovery process generally involves seroconversion from HBeAg to anti-HBe, reflecting a lowering of viral replication. Finally, immunized status generally refers to individuals who have received the hepatitis B vaccine and have developed protective antibodies, and HBeAg positivity does not correlate with this status.
