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.
PORTLAND, Ore.Sedia Biosciences Corporation of Portland Oregon, USA, announced today the commercial launch of a new product, the Sedia™ HIV-1 Limiting Antigen (LAg)-Avidity EIA for Dried Blood Spot Specimens. The new assay supplements its highly regarded HIV incidence assay, the Sedia™ HIV-1 Limiting LAg-Avidity EIA
9. Molecular Diversity. 10. assay (LAg-Avidity), BioRad-Avidity assay, CD4 cell count and viral load (VL). We evaluated 23,400 A limiting antigen avidity assay (HIV-1 LAg-Avidity EIA,. Performance of new LAg-Avidity EIA to measure HIV-1 incidence in a cross- sectional population: Swaziland HIV incidence measurement survey (SHIMS).
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 as non-recently infected. 2014-06-03 · Primary and follow-up HIV-1 positive plasma samples from individuals with well-defined dates of infection collected as part of the German Seroconverter Cohort provided specimens highly suitable for use in comparing the performance of three TRIs: the AWARE™ BED™ EIA HIV-1 Incidence test (BED-CEIA), Genetic systems HIV-1/HIV-2 Plus O EIA antibody avidity-based assay (BioRad Avidity) and Sedia™ HIV-1 LAg Avidity EIA (LAg Avidity).
How does the RTRI compare to the HIV-1 LAg-Avidity EIA? admin April 5, 2019 | 0. Both RTRI and LAg-Avidity EIA, developed in ILB/CDC, use the same gp41 multi-subtype protein and are based on the same principle of using limiting antigen to distinguish recent from long-term infections. However, the LAg-EIA is a laboratory-based assay requiring specialized equipment while RTRI is a rapid test in lateral flow format.
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 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. 2015-09-21 · 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 It is recommended that the studies conducted previously with the LAg-Avidity EIA should reanalyze their data using revised cutoff (ODn<1.5) for recent HIV infection classification and MDRI of 130 days as per our new analysis. This revision does not impact the raw data generated using the LAg-Avidity EIA, just the interpretation and use of the data.
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. Methods: The 15 cases with HIV seroconversion were found in a MSM observation cohort for calculating the HIV prevalence in Zhejiang.The subjects were conducted epidemiological investigation and sampled.The interval of infection

• Line We extended the concept of limiting antigen from EIA to rapid test format combining this with routine HIV diagnostic test to simultaneously achieve HIV diagnosis and LAg-Avidity EIA played a central role in measuring the impact of PEPFAR by estimating incidence in more than a dozen countries as part of Population -based HIV Impact Assessment (PHIA) surveys. Currently, over 50 countries are usi ng the LAg-Avidity EIA to monitor the status of the HIV epidemic nationally or in key populations. HIV-1 LAg-Avidity EIA dried blood spot and plasma kits were used for recency testing, with a rapid recency assay (Asante HIV-1 Rapid Recency Assay) also being applied in Siaya County. In Zimbabwe, we also ran the Maxim test kits on samples taken from female sex workers participating in a number of respondent driven sampling surveys.
