Interpretation of Hepatitis B and C Serology Results

Understanding Your Results

The Centers for Disease Control and Prevention recommends that a negative HBsAg with positive anti-HBs indicates immunity to hepatitis B, which could be from successful hepatitis B vaccination or recovery from a past hepatitis B infection 1, 2
A negative hepatitis C antibody test indicates that an individual has not been infected with hepatitis C virus, according to the MMWR Recommendations and Reports 3

The pattern of negative HBsAg with positive anti-HBs indicates immunity to hepatitis B, as stated by the MMWR Recommendations and Reports 2
Individuals who are not infectious and cannot transmit hepatitis B to others have likely developed immunity from vaccination or past infection 4

A negative hepatitis C antibody test result suggests that an individual has not been infected with hepatitis C virus, as indicated by the MMWR Recommendations and Reports 3

For individuals with certain medical conditions, such as chronic liver disease, HIV infection, or those requiring immunosuppressive therapy, monitoring of hepatitis B status may be recommended by the Centers for Disease Control and Prevention 5

The MMWR Recommendations and Reports suggest that individuals at ongoing risk for hepatitis B or C exposure, such as healthcare workers or those with multiple sexual partners, may require periodic testing 2, 3
Individuals receiving immunosuppressive therapy may need additional monitoring due to the risk of hepatitis B reactivation, even in those with resolved infection, as recommended by the Praxis Medical Insights 5

The Centers for Disease Control and Prevention, as reported in MMWR Recommendations and Reports, confirms that a serologic pattern of HBsAg non-reactive, HBsAb reactive, and HBcAb non-reactive indicates immunity to hepatitis B virus from successful vaccination 6
Individuals with this serologic pattern are immune to hepatitis B infection through vaccination, as confirmed by the presence of HBsAb without HBcAb, according to the MMWR Recommendations and Reports 6
The National Comprehensive Cancer Network indicates that if you require immunosuppressive therapy, you should be monitored for potential loss of immunity 7
The risk of HBV reactivation is minimal in individuals with vaccine-derived immunity, as they lack HBcAb, meaning they have no prior natural infection that could reactivate, as stated in the Journal of the National Comprehensive Cancer Network 7

No further routine testing is typically required in immunocompetent individuals, though annual screening with anti-HBs may be recommended in certain high-risk settings like dialysis units, as recommended by the American Society of Nephrology 8

The risk of HBV reactivation is minimal in individuals with vaccine-derived immunity because they lack HBcAb, meaning there is no prior natural infection that could reactivate, according to the National Comprehensive Cancer Network 9
