Hepatitis B Core Antibody

A Hepatitis B Core Antibody (anti-HBc) test detects antibodies produced in response to the core antigen of the hepatitis B virus. A positive result may indicate a current, past, or resolved hepatitis B infection and should be interpreted alongside other hepatitis B markers.

Doctor's Assessment Included

Reference Ranges

Expected result Negative

Anti-HBc shows whether you have ever had hepatitis B. Vaccination does not make this result positive — after vaccination anti-HBc is negative and anti-HBs is positive. A positive result does not mean you currently have an infection: it usually reflects an infection that cleared on its own, and in a low-prevalence country such as the Netherlands a positive result is also regularly a false positive. Discuss a positive result with your GP.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test detects antibodies against the hepatitis B core antigen (HBcAg). These antibodies appear early during infection and can persist for life. The test provides a qualitative result indicating whether anti-HBc antibodies are present, helping to determine exposure history to the hepatitis B virus.

Why It Matters

Anti-HBc is an important marker for determining hepatitis B exposure. It can help distinguish between individuals who have been vaccinated (anti-HBc negative) and those who have been infected (anti-HBc positive). Combined with other hepatitis B markers such as HBsAg and anti-HBs, it supports a comprehensive assessment of hepatitis B status.

When to Test

Testing may be recommended as part of hepatitis B screening, before starting immunosuppressive therapy, during blood donation screening, or when evaluating unexplained liver enzyme elevations. Consult a healthcare professional for guidance on whether this test is appropriate for your situation.

Recommendations

Male

If Low

Negative result indicates no prior Hepatitis B infection.

If High

Positive result indicates prior or current Hepatitis B infection. Consider further evaluation.

Lifestyle Tips

Support liver health by limiting alcohol consumption, maintaining a healthy weight, and eating a balanced diet. If you have not been vaccinated against hepatitis B, consult your healthcare provider about vaccination. Practise safe hygiene and avoid sharing personal items such as razors or toothbrushes.

Frequently Asked Questions

What does a positive anti-HBc result mean?
A positive anti-HBc result indicates that you have been exposed to the hepatitis B virus at some point. It does not distinguish between a current or past infection on its own. Additional tests such as HBsAg and anti-HBs are needed to determine your current hepatitis B status. Consult a healthcare professional for interpretation.
Can vaccination cause a positive anti-HBc result?
No, hepatitis B vaccination produces anti-HBs antibodies but does not produce anti-HBc antibodies. A positive anti-HBc result indicates natural exposure to the virus rather than vaccine-induced immunity.
