The two assays were performed as previously described (BED-CEIA, Calypte Biomedical Corp, Portland, OR; LAg-Avidity EIA, Sedia Biosciences Corp, Portland, OR) [12,24]. The samples were classified as recent or long-term infections according to the respective threshold values. The Sedia-LAg-Avidity assay is another commercially available antibody-single well based incidence assay. The assay measures high avidity antibodies against major variants of gp41 immunodominant regions among the HIV-1 group M viruses. LAg-Avidity is an indirect ELISA, using 0.1 M citrate buffer to dissociate low avidity antibodies.

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.

HIV-1 p24 Antigen Analytical Sensitivity In an internal study, the results demonstrated an antigen sensitivity of 14.78 pg/mL (range of 13.22 – 15.89 pg/mL) Evaluation of the limiting antigen avidity EIA (LAg) in people who inject drugs in Greece - Volume 145 Issue 2 The Sedia™ HIV-1 Limiting Antigen (LAg)-Avidity EIA is an in vitro single well quantitative limiting antigen avidity enzyme immunoassay for distinguishing recent HIV-1 infections from those which are long-term. 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.

This kit is intended as an aid in the diagnosis of HIV-1 and/or HIV-2 infection, including acute or primary HIV-1 infection.

Avidity EIA (LAg Avidity EIA), was developed primarily to detect and distinguish recent from long term HIV infection to estimate HIV incidence in cross-sectional surveys. Other related applications are: The LAg-Avidity EIA is developed by Centers for Diseases Control and Prevention (CDC). It is optimized, manufactured and distributed under 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.
