A positive anti-HBc total result means antibodies to the hepatitis B core antigen are present (IgM and/or IgG), indicating past exposure or current infection with hepatitis B. It is not produced by vaccination. Further testing—HBsAg, anti-HBs and sometimes HBV DNA—is needed to distinguish acute, chronic, resolved infection, or an isolated core-antibody result and to guide management.

The anti-HBc (hepatitis B core antibody) test typically costs about $20–$100 when paid privately, varying by country and laboratory. In low-cost markets it can be as little as $3–$15 (₹200–₹1,200); in some private US labs prices may reach $80–$120. Many public health services or insurance plans cover the test, making it free at point of care.

Anti-HBc (antibody to hepatitis B core antigen) indicates exposure to hepatitis B virus. It appears during acute infection and usually persists for life, so total anti‑HBc marks past or current infection. IgM anti‑HBc suggests recent/acute infection. Testing helps diagnose infection phases, detect occult HBV when HBsAg is negative, and distinguish natural infection from vaccination.

The HBc test detects antibodies to the hepatitis B core antigen to identify past or current hepatitis B infection. IgM anti‑HBc indicates recent (acute) infection, while total anti‑HBc shows prior exposure. It helps distinguish natural infection from vaccination (vaccines don’t produce core antibodies), and is used for screening (e.g., blood donors, pregnancy), diagnosis, and pre‑immunosuppression checks.

Anti‑HBc is an antibody marker, so treatment depends on the underlying hepatitis B status. If anti‑HBc alone with no active infection, no specific treatment—periodic monitoring. Acute HBV (IgM anti‑HBc) is mainly supportive; antivirals are used for severe or fulminant cases. For chronic HBV (HBsAg positive), long‑term antivirals (e.g., tenofovir, entecavir) or interferon are managed by a specialist; screen before immunosuppression.

An isolated anti‑HBc positive result indicates past or possible occult hepatitis B infection. Most blood services defer donors with anti‑HBc until further testing (HBsAg and HBV DNA). If confirmatory tests are negative and local policy permits, donation may be allowed; many centers, however, permanently or temporarily exclude anti‑HBc positives due to residual risk. Check your local blood service for specific rules.
