Persons with HIV Infection: The CDC and the US Preventive Services Task Force recommend syphilis screening should be performed at the initial HIV evaluation and at least annually thereafter in all sexually active persons with HIV 12) More frequent screening (every 3 to 6 months) is indicated for persons with HIV who have ongoing risk for acquiring syphilis Performance of an oral fluid rapid HIV-1/2 test: experience from four CDC studies AIDS 2006 20:1655-60 [PMID: 16868447] Crossref Medline Google Scholar 9 Branson B Wesolowski L Delaney K Mavinkurve M Dowling T Mackellar D Investigation of reports of excessive false-positive oral fluid rapid HIV tests Presented at 13th Conference on

Two sera in phase 3 were classified as HIV-negative by all rapid tests at the rural testing sites but were HIV-positive at the Honduran Central Laboratory and at CDC However since the purpose of this study was to measure performance of the tests and WHO algorithms under field conditions the field results were reported without correction

The Gen-Probe Aptima HIV-1 RNA qualitative assay was evaluated as an alternative to Western blot analysis for the confirmation of HIV infection using serum samples that were repeatedly reactive for HIV antibodies The Aptima HIV assay readily discriminated between HIV-1-infected and -uninfected individuals and effectively reduced the number of indeterminate results relative to Western blot

CDC and the Association of State and Territorial Public Health Laboratory Directors (ASTPHLD) conducted a workshop in Atlanta on October 24 1997 to discuss rapid HIV testing the potential health benefits and risks of reporting provisional rapid-test results and the feasibility of changing the recommendations of the PHS and ASTPHLD for reporting HIV-test results (5) ***** Workshop

A Quality Management Approach to Implementing

Technology advances in rapid diagnosis and clinical monitoring of human immunodeficiency virus (HIV) infection have been made in recent years greatly benefiting those at risk of HIV infection those needing care and treatment and those on antiretroviral (ART) therapy in sub-Saharan Africa However resource-limited geographically remote and harsh climate regions lack uniform access to

2 1 HIV testing algorithms WHO HIV testing guidelines recommend that specimens are first tested with the most sensitive rapid antibody POCT available If this test is non‐reactive individuals are considered HIV negative whereas if this test is reactive a second distinct assay is used 28

A two-test rapid testing algorithm (RTA) exists at 24 New Jersey sites including FQHCs community based organizations health departments and academic medical centers under the oversight of a centralized quality assurance structure (NJ HIV) At sites involved in the RTA program clients are initially tested by one of two rapid assays If either is positive a second rapid test (Unigold) is

In RLS HIV testing algorithms include a combination of two or three rapid tests usually in a serial algorithm depending on HIV prevalence this has produced suitable sensitivities and specificities and improved the accuracy of testing results in POC settings Countries decide on a testing algorithm serial or parallel to apply to their programs and use the right combination of HIV rapid

The CDC recommends CD4 testing every 3-6 months in all HIV-infected persons Two types of HIV resistance testing are available Genotypic assays detect genetic mutations in the coding regions of the protease and reverse transcriptase enzymes in HIV isolated from the patient Using the results standardized algorithms are applied to predict resistance to various antiretrovirals Phenotypic

Novel fourth generation screening and confirmatory human immunodeficiency virus (HIV) assays are now commercially available and incorporated into new diagnostic algorithms We report two cases involving a total of three patients which highlight the spectrum of false positivity for both the Abbott Architect p24 antigen/antibody assay and the confirmatory Multispot antibody differentiation test

Title: Rapid Test Algorithms for Diagnosis of HIV infection and Improved Linkage to Care The CDC policies guidelines terms and conditions stated in this announcement may differ from those used by the NIH Authority: Se ction 317 (k)(2) and 318 of the Public Health Service Act (42 U S C Sections 247b (k)(2) and 247(c) as amended

21 06 2013Detection of Acute HIV Infection in Two Evaluations of a New HIV Diagnostic Testing Algorithm — United States 2011–2013 The highly infectious phase of acute human immunodeficiency virus (HIV) infection defined as the interval between the appearance of HIV RNA in plasma and the detection of HIV-1–specific antibodies contributes disproportionately to HIV transmission (1)

CDC reports prevalence as the number of persons living with HIV infection in a given population at a given time and also reports prevalence rates calculated per 100 000 population Uses of these data: Prevalence is useful for planning and resource allocation as it reflects the number of people currently needing care and treatment services for HIV infection

The World Health Organization recommends that countries conduct two phase evaluations of HIV rapid tests (RTs) in order to come up with the best algorithms In this report we present the first ever such evaluation in Uganda involving both blood and oral based RTs The role of weak positive (WP) bands on the accuracy of the individual RT and on the algorithms was also investigated

HIV-testing algorithms for preexposure prophylaxis (PrEP) should be optimized to minimize the risk of drug resistance the time off PrEP required to evaluate false-positive screening results and costs and to expedite the start of therapy for those confirmed to be infected HIV rapid tests (RTs) for anti-HIV antibodies provide results in less than 1 h and can be conducted by nonlicensed staff
