Comparative evaluation of the Bio-Rad Geenius HIV-1/2 Confirmatory Assay and the Bio-Rad Multispot HIV-1/2 Rapid Test as an alternative differentiation assay for CLSI M53 algorithm-I

Evaluation of the Bio-Rad Geenius HIV-1/2 test as a confirmatory assay

OBJECTIVES We have evaluated the recently Conformité Européenne (CE)-marked Bio-Rad Geenius human immunodeficiency virus (HIV)1/2 as a rapid and simple alternative to western blot for confirmation of HIV screening results. METHODS A total of 160 serum samples were tested: 44 HIV-1 reactive samples by a fourth-generation Murex HIV Ag/Ab and/or Vidas HIV Duo Ultra, five HIV-2 reactive samples, ...

Evaluation of the Bio-Rad Geenius HIV 1/2 assay as an alternative to the INNO-LIA HIV 1/2 assay for confirmation of HIV infection.

The Bio-Rad Geenius HIV 1/2 assay was evaluated as an alternative to the INNO-LIA HIV 1/2 assay for the confirmation of HIV infection in 198 serum samples reactive to 4th-generation HIV enzyme immunoassays (EIAs). The Geenius assay correctly identified 85% of the samples, compared to 75% identified by the INNO-LIA assay, reduced the number of indeterminate results, and shortened the overall tur...

Evaluation of Bio - Rad Geenius TM HIV - 1 / 2 as a confirmatory assay for 1 detection of HIV - 1 / 2 antibodies

Evaluation of the Bio-Rad Geenius HIV 1/2 Confirmation Assay as an Alternative to Western Blot in the Korean Population: A Multi-Center Study

Recently updated recommendations for diagnosis of HIV infection suggest a new diagnostic algorithm including HIV-1/HIV-2 antibody differentiation immunoassay instead of western blot (WB) as a confirmatory testing. We evaluated Bio-Rad Geenius HIV1/2 confirmation assay as a simple and reliable alternative to WB in the Korean population with low HIV prevalence. The Geenius HIV1/2 was performed in...

Comparative performance of the Geenius™ HIV-1/HIV-2 supplemental test in Florida's public health testing population.

BACKGROUND The Centers for Disease Control and Prevention (CDC) published updated guidelines in 2014 for the laboratory diagnosis of HIV in the United States, which recommend use of a supplemental immunoassay (IA) that differentiates HIV-1 from HIV-2 after a repeatedly reactive HIV-1/2 antigen/antibody "Combo" screening test. In October 2014, Bio-Rad Laboratories introduced the FDA-cleared Geen...
