Significado de la reactividad aislada anti-HBc como único marcador de infección de la hepatitis B

The anti-HBc alone pattern is a frequent finding, particularly in patients > 65 years old and in HCV or HIV coinfected patients. Although HBV-DNA was detected in a small percentage of cases, this test could be indicated in certain clinical situations (liver disease, coinfection, donors). Furthermore, this profile seems to be related with HCV infection; hence, we consider anti-HCV detection necessary in all patients with anti-HBc alone.
