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 Pooled viral RNA testing shortens the window period to a median of 17 days (95% CI, 13-28 Days). Although it is not the standard of care to use this test for diagnosis, in communities with high HIV prevalence, this test has a significantly improved negative predictive value over 3rd and 4th generation tests for detecting acute HIV infections.

Sexual Health. HIV index value. 1 year ago. Asked for Male, 24 Years. Did HIV 1&2 and p24 antigen test after 1 month of exposure from Lal path labs..Its non-reactive but index value is very high 0.847, I have fear next time it may reach 1. Why is it too high? HIV-2–endemic population 99.79% (95% CI: 98.82–99.99%). Conclusions: The results of this study show that the Atellica IM HIV Ag/Ab Combo (CHIV) Assay is a precise and accurate fully automated qualitative method to simultaneously detect the presence of both HIV p24 antigen and HIV antibodies in human serum or plasma. The Jul 26, 2018 · Detection of acute HIV infection is critical for HIV public health and diagnostics. Clinical fourth-generation antigen (Ag)/antibody (Ab) combination (combo) and p24 Ag immunoassays have enhanced detection of acute infection compared to Ab-alone assays but require ongoing evaluation with currently circulating diverse subtypes. If test specificity is 99.8%, results for approximately 20 specimens will be false-positive. In this case, of the 220 with positive results (200 true-positives plus 20 false-positives), 91% are actually infected with HIV. The number of true positives far exceeds the number of false positives. Low prevalence: If HIV prevalence is much lower (0.1 JKWLPiz.
