Wesolowski LG, Delaney KP, Hart C, et al. Performance of an alternative laboratory-based algorithm for diagnosis of HIV infection utilizing a third generation immunoassay, a rapid HIV-1/HIV-2 differentiation test and a DNA or RNA-based nucleic acid amplification test in persons with established ...
For HIV, HCV and HTLV antibody based screening strategies immunoblots are often used to confirm the presence of antibody. However, immunoblots are relatively costly and can have poor specificity making it important to optimise the specificity of the screening algorithm. Immunoblotting subsequent to a...
The 2014 HIV diagnostic testing algorithm recommended by the CDC is based on newer tests that are more sensitive for acute infection.2,3The algorithm is designed to (1) detect acute infections more often; (2) reduce the frequency of indeterminate results on supplemental testin...
a sample is usually sent to a central facility for an RNA or other confirmatory test. If the first two tests have divergent results, the first test is repeated and if they are still divergent, the advice is to wait 14 days to see if they both become positive. While this algorithm is ...

2. HIV-1 testing algorithm The AxSym HIV Ag/Ab Combo assay is used for all routine HIV screening requests. An input of 200 μl serum or plasma is needed for the test. In general, when the HIV Ag/Ab Combo result is non-reactive (negative) then the HIV serology is finished. The pati...
To address this situation, a concerted effort was made among public health agencies to develop a new testing algorithm that provided the following: (1) earlier and more accurate detection of HIV-1, including acute infection; (2) faster turnaround time for results; (3) more accurate diagnosis ...
These results, along with considerations for ease of use, test sensitivity, and potential for scale-up, helped the MOH determine the most efficient and cost-effective HIV testing algorithm to adopt. “The analysis has enabled the Ministry of Health to switch in February 2013 to a more cost-...
Mbale hospital, in line with the Uganda national guidelines, a sequential HIV testing algorithm, with same-day results is used. The testing algorithm includes three rapid tests used on one blood sample. ‘Determine’ is used for first screening, STAT-PAK for a second test and Uni-Gold as a...
