Here are potential causes of a reactive Hepatitis B Surface Antigen (HBsAg) Test result.
Potential Causes | Description |
---|---|
Active Hepatitis B Infection | A reactive result typically indicates an active Hepatitis B virus infection. |
Chronic Hepatitis B | Persistent presence of HBsAg may suggest chronic Hepatitis B. |
Acute Hepatitis B | In the early stages of acute infection, HBsAg levels may be high. |
Carrier State | Some individuals can carry the virus without symptoms, leading to a reactive HBsAg result. |
Here are potential causes of a non-reactive Hepatitis B Surface Antigen (HBsAg) Test result.
Potential Causes | Description |
---|---|
No Hepatitis B Infection | A non-reactive result indicates the absence of an active Hepatitis B virus infection. |
Successful Vaccination | Vaccination against Hepatitis B can lead to non-reactive HBsAg results. |
Past Infection and Recovery | Individuals who have recovered from Hepatitis B may show non-reactive results, although other markers like anti-HBc may be present. |
False Negative Result | Rarely, a non-reactive result may occur in individuals with low viral loads or during the early stages of infection. Confirmatory tests may be necessary. |
