Fig. 1. HIV testing algorithm. Ag = antigen; Ab = antibody; WB = Western blot. When the HIV Ag/Ab Combo result is reactive the presence of specific anti-HIV antibodies is confirmed by HIV-1/HIV-2 Western blot a
As MJ4/Gag chimeric vectors encoded patient Protease up to residue 40, partial Protease was examined for resistance mutations, as defined by the Stanford Resistance Algorithm (http://hivdb.stanford.edu). Neither major nor minor resistance mutations in protease were identified, but polymorphisms were...
Zambia’s national HIV testing algorithm specifies use of two rapid blood based antibody assays, Determine®HIV-1/2 (Inverness Medical) and if positive then Uni-GoldTM Recombigen HIV-1/2 (Trinity Biotech). Little is known about the performance of oral fluid based HIV testing in Zambia. The...
After the interpretation of HIV-1 group M subtype B mutations, a refined algorithm for the other group M subtypes was developed followed by the interpretation of HIV-1 group O and HIV-2 mutations. The process of improvement is ongoing, due to the better understanding and interpretation of ...
There are ample of tests which can detect HIV starting from the point of care testing to confirmatory test. The test algorithm to be followed has been released by the Centre for Disease Control (CDC) and Association of Public Health Laboratories (APHL) as well as the national organizations in...
DRM analyses in PR-RT and IN regions were performed in the Stanford HIV Drug Resistance Database (https://hivdb.stanford.edu)59 using Stanford HIVdb Program Genotypic Resistance Interpretation Algorithm (https://hivdb.stanford.edu/hivdb/by-sequences)60. Inferred levels of resistance of HIV-1...

Fig. 1. HIV Testing Algorithm. A risk-assessment questionnaire including general health, behavioral and sexual risks was administered by the study staff at Visit 1 and every 6 months thereafter. Participants who acquired HIV infection during the course of the study underwent CD4 + T cell count ...
The algorithm for HIV rapid testing consisted of an ini- tial screening with the rapid test, Determine HIV1/2. If the test result was negative, the participant was given a negative diagnosis with no further rapid testing. If the test result was positive, the sample was retested with the ...
Interpretation of drug resistance mutations DRMs of the protease-reverse transcriptase regions were analyzed using the Stanford HIVDR database algorithm version 8.1 [29]. PI/r, NRTIs and NNRTIs effectiveness were interpreted using the genotypic scoring system for drug susceptibility with the following ...
