Ett positivt anti-HBc IgM-test indikerar en akut hepatit B-virusinfektion men kan också indikera reaktivering av en tidigare okänd kronisk hepatit B-infektion. Den senare har dock som regel betydligt högre HBV-DNA-mängder. HBsAg-positivitet samt anti-HBc IgG-positivitet indikerar kronisk hepatit B-virusinfektion.

The IgM  In acute infection, high levels of IgM anti-HBc appear which persist for 3-4 months and are then replaced by IgG anti-HBc. High titer of IgG anti-HBc can be found in   Background/Aims: We determined the diagnostic significance of IgM anti-HBc by a rapid, fully automated microparticle enzyme immunoassay (IMx CORE-M) in  The MONOLISA Anti-HBc IgM EIA is an enzyme immunoassay intended for use in the qualitative detection of IgM antibodies to hepatitis B core antigen (anti-HBc   The MONOLISA Anti-HBc IgM EIA is an enzyme immunoassay intended for use in the qualitative detection of IgM antibodies to hepatitis B core antigen (anti-HBc   With respect to the diagnosis of acute hepatitis B, IgM anti-HBc is arguably the best serologic marker. the absence of IgM anti-HBc), this indicates chronic HBV infection. HBeAg: Hepatitis B “e” antigen is a marker of a high degree of HBV infectivity, and it correlates  IgM antibody to hepatitis B core antigen (IgM anti-HBc):. Positivity indicates recent infection with hepatitis B virus (<6 mos). Its presence indicates acute infection.

Tests for detecting anti‑HBc IgM antibodies are used, in conjunction with HBsAg determinations, to identify acute hepatitis B viral infections. An acute attack of hitherto non‑diagnosed chronic hepatitis B clinically resembles an acute hepatitis B infection and cannot be distinguished from this with certainty by determining the anti‑HBc IgM.

antibody (anti-HBc): Appears at the onset of symptoms in acute hepatitis B and persists for life. The presence of anti-HBc indicates previous or ongoing infection with hepatitis B virus in an undefi ned time frame. IgM antibody to hepatitis B core antigen (IgM anti-HBc): Positivity indicates recent infection with hepatitis B virus (<6 mos).

HBcAb-IgM ELISA Diagnostic Kit for IgM Antibodies to Hepatitis B Virus Core Antigen (ELISA) In chronic hepatitis, however, spikes of anti-HBc IgM synthesis are present, confirming reactivation of HBV in hepatocites and giving origin to permanent IgM low titers. Presence of IgM and total anti-HBc indicates an ongoing or recent HBV infection.

Anti-HBc IgG and IgM appear shortly after the symptoms and onset of the virus surface antigen (HBsAg). IgM arrives first and is then replaced by IgG. Anti-HBc IgM是B型肝炎「近期感染」的指標,通常出現於B肝感染的早期,持續數個月後消失。. 因此Anti-HBc IgM陽性至少代表二個意義:一是「初次感染」,二是「近期感染」。.

Anti-HBc IgM increases rapidly, peaks during the acute infection stage of HBV infection, and then falls to a relatively low level as the patient recovers or becomes a chronic carrier. Anti-HBc IgM is useful in the diagnosis of acute HBV infection even when HBsAg concentrations are below the sensitivity of the diagnostic assay.

După dispariţia antigenului HBs şi înainte de apariţia anticorpilor anti-HBs (“fereastra imunologică”), anticorpii anti-HBc şi anticorpii anti-HBc-IgM pot fi singurii indicatori ai prezenţei hepatitei B acute. EIA was used to study the titers of IgM anti-HBc in 38 patients with chronic hepatitis B, 10 with acute viral hepatitis B and 18 patients with D-infection (6 with coinfection and 12 with D-superinfection) depending on the presence of HBe/anti-HBe. Anti-HBc IgM may be the only serologic marker of a recent hepatitis B infection detectable following the disappearance of hepatitis B surface antigen (HBsAg) and prior to the appearance of hepatitis B surface antibody (anti-HBs) (ie, serologic window period).
