Laboratoires Réunis Junglinster, Luxemburg und Institut für Medizinische Virologie, Universitatskliniken Frankfurt, Frankfurt, Germany
J Med Virol 78:S59-65. 2006..There is also a need for more complete epidemiological data on the prevalence of HBsAg mutants especially for G145R and assays for the (differential) screening of mutants need to be developed and evaluated... - Evaluation of a new automated assay for hepatitis B surface antigen (HBsAg) detection VIDAS HBsAg UltraBernard Weber
Laboratoires Réunis, Junglinster, Luxembourg, Germany
J Virol Methods 135:109-17. 2006..6% (AxSYM HBsAg v2). In conclusion, the VIDAS HBsAg Ultra is highly sensitive and specific and represents an improvement for the detection of HBsAg in routine diagnostic laboratories... - Recent developments in the diagnosis and monitoring of HBV infection and role of the genetic variability of the S geneBernard Weber
Centre Langwies, Laboratoires Réunis, L 6131 Junglinster, Luxembourg
Expert Rev Mol Diagn 5:75-91. 2005.... - Genetic variability of the S gene of hepatitis B virus: clinical and diagnostic impactBernard Weber
Laboratoires Réunis Junglinster, Luxembourg and Institute of Medical Virology, University Hospital Frankfurt Main, Germany
J Clin Virol 32:102-12. 2005..There is also a need for more complete epidemiological data on the prevalence of HBsAg mutants and strategies for the (differential) screening of mutants need to be developed and evaluated... - Detection of an acute asymptomatic HBsAg negative hepatitis B virus infection in a blood donor by HBV DNA testingBernard Weber
Laboratoires Réunis, Junglinster, Centre Langwies, L 6131 Junglinster, Luxembourg
J Clin Virol 32:67-70. 2005..Since the viral load in chronic isolated anti-HBc positive carriers is low, there is a potential risk for failure of HBV DNA detection with pool-PCR in blood donors. Anti-HBc screening would reduce the residual risk... - Reduction of the diagnostic window in three cases of human immunodeficiency-1 subtype E primary infection with fourth-generation HIV screening assaysB Weber
Laboratoires Réunis Kutter Lieners Hastert, Junglinster, Luxembourg

Laboratoires Réunis Kutter Lieners Hastert, Junglinster, Luxembourg
J Clin Microbiol 41:135-43. 2003..The specificity on repeatedly tested samples was equivalent to that of the alternative assays. The rapid turnaround time, primary tube sampling, and on-board dilution make it an interesting assay system for clinical laboratory diagnosis... - Multicenter evaluation of a new automated fourth-generation human immunodeficiency virus screening assay with a sensitive antigen detection module and high specificityBernard Weber
Laboratoires Réunis Kutter Lieners Hastert, Junglinster, Luxembourg

Med Microbiol Immunol 196:247-52. 2007..4-100%) but differed considerably in specificity (84-99%). Failure to detect HBsAg antigen and differences in signal intensity were mainly associated with mutations in the preS/S gene outside the "a" determinant... - High-throughput purification of viral RNA based on novel aqueous chemistry for nucleic acid isolationMichael K Hourfar
Institute of Transfusion Medicine and Immunohaematology, German Red Cross, Johann Wolfgang Goethe University, Frankfurt, Germany
Clin Chem 51:1217-22. 2005..However, commercially available magnetic-bead-based assays either lack the sensitivity required for viral diagnostics or are disproportionately expensive... - Modifications and substitutions of the RNA extraction module in the ViroSeq HIV-1 genotyping system version 2: effects on sensitivity and complexity of the assayMartin Stürmer
Institut fur Medizinische Virologie, J W Goethe Universitat, Frankfurt, Germany
J Med Virol 71:475-9. 2003..This is of great importance as it avoids further time- and cost-intensive steps... - Regional spread of HIV-1 M subtype B in middle-aged patients by random env-C2V4 region sequencingMartin Stürmer
