The BioPlex HIV Ag-Ab assay is also intended for use in testing plasma specimens to screen organ donors when specimens are obtained while the donor’s heart is still beating. Apr 1, 2022 · However, for females, the optimal cutoff value was 26.97 with the highest sum of sensitivity (100.00%) and specificity (100.00%). Conclusions: For the Architect HIV Ag/Ab Combo, the optimal cutoff value needs to be set for the different genders to predict the final status of HIV infection reliably. The median AI values obtained with AxSYM HIV 1/2 gO were compared to those obtained with Architect HIV Ag/Ab Combo, using the Mann-Whitney test. For each sample, the correlation between the AI values obtained with the two assays was calculated with the parametric test of the Pearson correlation coefficient (r). For the qualitative AI results (i Sep 30, 2016 · If the number is higher than 1.0 it means you are positive. If the number on your test is less that 1.0 it means you are negative. So long as it is below 1.0 the number itself has little meaning. For example, 0.68 is not worse than 0.38. A higher number below 1.0 does NOT indicate a higher chance of having HIV. HIV-1 p24 antigen (Ag) and antibodies (Ab) to HIV-1 and HIV-2 in human blood. The test specimen can be serum, plasma, fingerstick or venous whole blood. The test is intended as a rapid test to detect free non immunocomplexed HIV-1 p24 antigen and antibodies to HIV-1/ HIV-2 from infected individuals. SUMMARY AND EXPLANATION OF THE TEST .
