Viral load monitoring is used by HIV-positive people to develop a plan for their personal treatment of HIV/AIDS. [1] A count of the viral load is routine before the start of HIV treatment. [1] If the treatment is not changed, then viral load is monitored with testing every 3–4 months to confirm a stable low viral load. [1]
A different version of this test is intended for use in conjunction with clinical presentation and other laboratory markers of disease progress for the management of HIV-1-infected patients. In the RT-PCR test, viral RNA is extracted from the patient's plasma and is treated with reverse transcriptase (RT) to convert the viral RNA into cDNA.
At this point, seroconversion, the development of antibodies, occurs and the CD4 T cell counts begin to recover as the immune system attempts to fight the virus, marking the HIV set point. The higher the viral load at the set point, the faster the virus will progress to AIDS; the lower the viral load at the set point, the longer the patient ...
A 2010 review study by Puren et al. [2] categorizes viral load testing into three types: (1) nucleic acid amplification based tests (NATs or NAATs) commercially available in the United States with Food and Drug Administration (FDA) approval, or on the market in the European Economic Area (EEA) with the CE marking; (2) "Home–brew" or in-house NATs; (3) non-nucleic acid-based test.
Individuals who are in this phase are still infectious. During this time, CD4 + CD45RO + T cells carry most of the proviral load. [8] A small percentage of HIV-1 infected individuals retain high levels of CD4+ T-cells without antiretroviral therapy. However, most have detectable viral loads and will eventually progress to AIDS without treatment.
An HIV-positive person who has an undetectable viral load as a result of long-term treatment has effectively no risk of transmitting HIV sexually. [ 15 ] [ 16 ] Campaigns by UNAIDS and organizations around the world have communicated this as Undetectable = Untransmittable . [ 17 ]
The studies demonstrating that U=U is an effective strategy for preventing HIV transmission in serodiscordant couples so long as "the partner living with HIV [has] a durably suppressed viral load" include: [88] Opposites Attract, [89] PARTNER 1, [43] PARTNER 2, [90] [91] (for male–male couples) [88] and HPTN052 [92] (for heterosexual couples ...
Modern HIV testing is extremely accurate, when the window period is taken into consideration. A single screening test is correct more than 99% of the time. [119] The chance of a false-positive result in a standard two-step testing protocol is estimated to be about 1 in 250,000 in a low risk population. [120]
