A negative result rules out HIV exposure, while a positive one must be followed by an HIV-1/2 antibody differentiation immunoassay to detect which antibodies are present. This gives rise to four possible scenarios: 1. HIV-1 (+) & HIV-2 (−): HIV-1 antibodies detected; 2. HIV-1 (−) & HIV-2 (+): HIV-2 antibodies detected; 3.
HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells. [88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
Serostatus is a term denoting the presence or absence of particular antibodies in an individual's blood. An individual's serostatus may be positive or negative. During seroconversion, the specific antibody being tested for is generated. [13]
Performance of medical tests is often described in terms of: Sensitivity: The percentage of the results that will be positive when HIV is present; Specificity: The percentage of the results that will be negative when HIV is not present. All diagnostic tests have limitations, and sometimes their use may produce erroneous or questionable results.
The term serostatus is commonly used in HIV/AIDS prevention efforts. In the late 20th and early 21st centuries, social advocacy has emphasized the importance of learning one's HIV/AIDS serostatus in an effort to curtail the spread of the disease.
An HIV antibody test usually detects the HIV antibodies within two to eight weeks, but can have a valid negative result for a long as 2 to 6 months after initial infection. Viral load tests can also be used to diagnose HIV infection, especially in children under 18 months born to mothers with HIV, where the presence of maternal antibodies ...

Women with HIV have been shown to have decreased fertility which can affect available reproductive options. [119] In cases where the woman is HIV negative and the man is HIV positive, the primary assisted reproductive method used to prevent HIV transmission is sperm washing followed by intrauterine insemination (IUI) or in vitro fertilization (IVF
