Table of Contents HIV PCR (polymerase chain reaction) NAT (nucleic acid test) HIV is the abbreviation for the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome
HIV symptoms which may present in acute HIV infection: These are nonspecific symptoms and can present with other infections; consequently, they are unreliable indicators of HIV infection.
Remember, there is no HIV cure.
HIV window period is the time from HIV infection until a HIV Test can detect any change. Within the HIV window period, the HIV Test would be negative. During this period, the HIV viral load is extremely high, thus making the person highly infectious.
References HIV Test
- 4 weeks after exposure, a negative 4th generation HIV ELISA Test "is very reassuring / highly likely to exclude HIV infection."
- 12 weeks after exposure, a negative 3rd generation HIV ELISA Test "would definitively exclude HIV infection."
HIV ELISA (Enzyme-linked immunosorbent assay) test generations:
References HIV rapid test (20 minutes to results) Two types are available:
- 1st generation: HIV-1 IgG antibody
- 2nd generation: HIV-1 & HIV-2 IgG antibodies
- 3rd generation: HIV-1 & HIV-2 IgG & IgM antibodies
- 4th generation: HIV-1 & HIV-2 IgG & IgM antibodies and HIV p24 antigen
Note: If the clinic attendance is only for the HIV rapid test, then consultation fees are not added.

Individuals are eligible for HIV PEP Treatment if all the following criteria are met:
Prompt antiviral therapy may reduce the risk of HIV transmission by as much as 80%.
- less than 72 hours has elapsed since exposure;
- the exposed individual is not known to be HIV infected;
- the person who is the source of exposure is HIV infected or has unknown HIV status;
- mucous membrane or non-intact skin was exposed to a potentially infectious body fluid;
For optimal efficacy, antiretroviral therapy should be started as soon as possible, ideally within 1 hour of exposure. So that you can remain HIV negative.
The medications and dosages are the same as those used for lifelong treatment of HIV patients. However, for HIV PEP treatment, it is taken for only a month.

Do People Know I’m Poz?: Factors Associated with Knowledge of Serostatus Among HIV-Positive African Americans’ Social Network Members
Wed, 22 Apr 2015 20:36:02 +0100 | AIDS and Behavior
We examined how functional social support, HIV-related discrimination, internalized HIV stigma, and social network structure and composition were cross-sectionally associated with network members’ knowledge of respondents’ serostatus among 244 HIV-positive African Americans in Los Angeles. Results of a generalized hierarchical linear model indicated people in respondents’ networks who were highly trusted, well-known to others (high degree centrality), HIV-positive, or sex partners were more likely to know respondents’ HIV serostatus; African American network members were less likely to know respondents’ serostatus, as were drug-using partners. Greater internalized stigma among respondents living with HIV was associated with less knowledge of their seropositivity within their soci...

Not only has the prevalence of HIV dropped to a commendable 3.1 per cent from the about 3.8 per cent it peaked between 2004-2005, the amount of new HIV infection has also dropped significantly to less than 0.22 per cent (about 220,394 cases of infection) from a worrying peak of 0.49 (about 348, 564 cases) per cent in 2003.
