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...

an HIV-1 RNA assay”. The FDA says a test “cleared by the FDA for the diagnosis of acute HIV infection” should be used. This could be an RNA test, but if a fourth-generation
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 ...
The likelihood equation is solved using an iterative algorithm, and a simulation study shows that our procedure yields very accurate estimates at a fraction of the cost of existing procedures. 1998 John Wiley & Sons, Ltd.doi:10.1002/(SICI)1097-0258(19980715)17:133.0.CO;2-K...
HIV counseling and testing services are critical for individuals to access HIV prevention and treatment. Unfortunately, the standard HIV testing algorithm is complex and includes the use of a sensitive enzyme immunoassay (EIA), followed by a Western blot if the EIA is positive. This process can ...
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...
Based on the yield of Xpert in previous studies, the added sensitivity of Xpert Ultra and the expected proportion of participants with criteria for LAM testing, we assumed that the current WHO recommended algorithm will diagnose 19% of participants with bacteriologically confirmed TB. We have ...
Researchers will not have access to the algorithm. Only the software developer and biostatistician will be able to view the assignments in the data. Implementation Youth will be enrolled sequentially within the stratification group (or “bin”). Once a “bin” is full (e.g., White non-...
