Detection of HBsAg mutants

Journal of Medical Virology, 2006
HBsAg screening is carried out routinely to detect hepatitis B virus (HBV) infection. The immunoassays used employ capture antibodies often having specificity for epitopes present on the antigenic (a) determinant of the HBsAg. Loss of detection may occur due to mutations within and/or outside of the a determinant that affect conformational epitope ...

HBsAg blood screening and diagnosis: performance evaluation of the ARCHITECT HBsAg qualitative and ARCHITECT HBsAg qualitative confirmatory assays

Diagnostic Microbiology and Infectious Disease, 2011
A low initial reactive rate for screening assays is important for time- and cost-effective infectious disease testing. Therefore, the new ARCHITECT HBsAg Qualitative screening assay, in conjunction with the new ARCHITECT HBsAg Qualitative Confirmatory assay, was introduced.

Mutation of the “a” Determinant of HBsAg with Discordant HBsAg Diagnostic Kits

Viral Immunology, 2004
Sera from 1003 in- and out-patients were investigated for hepatitis B surface antigen (HBsAg) mutation at Siriraj Hospital, Bangkok, Thailand. Individual samples were screened using two commercial HBsAg kits on automatic machine-based assays set up in parallel. The first kit was a sandwich ELISA kit that used monoclonal capture/monoclonal conjugate and

Circulating immune complexes in HBsAg-positive and HBsAg-negative chronic liver diseases

La Ricerca in Clinica e in Laboratorio, 1984
Circulating immune complexes (CIC) were investigated by the fluid-phase C1q-binding test in serum samples from 131 subjects with various clinical types of HBsAg-positive and HBsAg-negative chronic hepatitis diagnosed on both clinical and laboratory criteria, including liver biopsy; serum samples from 28 asymptomatic HBsAg carriers and 75 healthy ...

Hepatitis B Surface Antigen (HBsAg) and Antibody to HBsAg

JAMA, 1977
The prevalence rates of serum hepatitis B surface antigen (HB s Ag) and antibody to HB s Ag (anti-HB s ) were 5.6% and 34% in 144 homosexual men in Seattle. Prevalence rates were only 0.9% and 3.6% in 111 heterosexual male venereal disease clinic patients with nongonococcal urethritis, and also 0.9% and 3.6% in 111 healthy men undergoing routine ...

[Incidence of HBsAg in persons living with HBsAg carriers].

Quaderni Sclavo di diagnostica clinica e di laboratorio, 1976
The prevalence of HBsAg was studied, by Counterelectrophoresis and Radioimmunoassay, in 232 household contacts of 65 HBsAg carriers. The overall incidence of HBsAg in household contacts was 14,65%, as compared with the generally accepted figure of about 1% in the general population in Italy. As far as the prevalence of HBsAg and abnormal liver function

HBsAg confirmation: an experimental test

Clinical and Diagnostic Virology, 1996
The specificity of HBsAg testing is to be confirmed with antibody blocking to avoid false positive results.To test the experimental HrAb HBsAg-blocking activity and to use this new antibody in the verification of repeatedly reactive HBsAg blood serum samples.HbsAg screening of three quality control panels was followed by a comparative confirmatory test

HLA Antigens in HBsAg Infection

Vox Sanguinis, 1979
Abstract. The HLA typing of hemodialysis patients and normal subjects suggests a negative association of B8 and positive association of B5 with the development of anti‐HBs and a negative association of BW35 with HBsAg antigenemia.
