Conference: Conference on Retroviruses and 2012-03-27 Determination of mean duration of recency and false recent rate for estimation of HIV-1 incidence with LAg-Avidity EIA in China International Conference on HIV/AIDS, STDs, & STIs October 24-25, 2013 Holiday Inn Orlando International Airport, Orlando, FL, USA. Jiang Yan. the LAg-Avidity EIA – a simple, rapid laboratory test that can simultaneously diagnose HIV and identify if an infection is recent – that was used in the PHIA surveys to directly measure population incidence. The Sedia™ HIV-1 LAg-Avidity EIA is the leading commercial HIV incidence assay used by epidemiologists, researchers and public health scientists as an … 2014-12-01 2015-02-24 Development of more accurate HIV tests for recent infection, such as the Sedia™ HIV-1 LAg-Avidity EIA, for surveillance of the HIV epidemic and estimation of HIV incidence rates, has been an important goal for HIV scientists for the past several years, since the alternative is to track large cohorts of at risk persons over a long time and monitor the frequency of new infections that occurs. The Maxim HIV-1 LAg-Avidity EIA uses US CDC developed technology and is designed for surveillance purposes such as estimating HIV-1 incidence in a population, monitoring and evaluating HIV intervention programs, and recognizing those high-incidence populations so that prevention research, vaccine trials, and resources are most appropriately utilized.

The Maxim HIV-1 Limiting Antigen Avidity (LAg-Avidity) EIA Test is an in vitro 96-well format enzyme immunoassay that measures the increasing avidity of HIV antibodies from liquid serum/plasma or dried blood spot eluted specimen after seroconversion. Antibody avidity reflects relative Methods A total of 2737 longitudinal specimens collected from 259 seroconverting individuals infected with diverse HIV-1 subtypes were tested with the LAg-Avidity EIA as previously described. Data were analyzed for determination of MDRI at ODn cutoffs of 1.0 to 2.0 using 7 statistical approaches and sub-analyzed by HIV-1 subtypes. The Sedia™ HIV-1 LAg-Avidity EIA is the leading commercial HIV incidence assay used by epidemiologists, researchers and public health scientists as an accurate laboratory tool to identify recent Maxim HIV-1 Limiting Antigen Avidity (LAg-Avidity) DBS EIA Kit, 192 Tests The Maxim HIV-1 Limiting Antigen-Avidity Dried Blood Spot (DBS) EIA is an in-vitro quantitative limiting antigen (LAg) avidity enzyme immunoassay for distinguishing recent HIV-1 infections from those which are long-term. An instructional video for Maxim Biomedical's LAg-Avidity EIA Test Kit for Dried Blood Spot (DBS) specimens (92003).This video is for training purposes only. LAg-avidity EIA and BED CEIA.

The assay is intended for use with liquid serum or plasma specimens. The Maxim HIV-1 LAg-Avidity EIA uses US CDC developed technology and is designed for surveillance purposes such as estimating HIV-1 incidence in a population, monitoring and evaluating HIV intervention programs, and recognizing those high-incidence populations so that prevention research, vaccine trials, and resources are most appropriately utilized. CDC/DGHA will provide training and technical assistance for laboratories wanting to use the LAg-Avidity EIA. To improve the accuracy of recent HIV classification, it is recommended that the LAg-Avidity EIA and other assays be used in an algorithm where assay-recent specimens are further tested for HIV RNA level and/or for the presence of ARTs to classify specimens with low viral load and individuals on ART … Objective: To evaluate the applicability of limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA, LAg for short) in determining the new HIV-1 infection status of MSM population with seroconversion and make correlation analysis of other biological indicators.
