    en.wikipedia.org/wiki/Viral_load_monitoring_for_HIV

    CD4 testing shows the strength of the immune system, but does not report viral activity. As established by the Centers for Disease Control and Prevention (CDC), a person with HIV and a CD4 count below 200 or a CD4 percentage below 14% is considered to have AIDS. [5] An increased CD4 count can result from an immune response to an infection or a ...

    en.wikipedia.org/wiki/CDC_Classification_System...

    In 1993, the CDC added pulmonary tuberculosis, recurrent pneumonia, and invasive cervical cancer to the list of clinical conditions in the AIDS surveillance case definition published in 1987 and expanded the AIDS surveillance case definition to include all HIV-infected persons with CD4+ T-lymphocyte counts of less than 200 cells/uL or a CD4 ...

    The CD4 T-cell count is not an HIV test, but rather a procedure where the number of CD4 T-cells in the blood is determined. A CD4 count does not check for the presence of HIV. It is used to monitor immune system function in HIV-positive people. Declining CD4 T-cell counts are considered to be a marker of progression of HIV infection.

    In 1993, the CDC added pulmonary tuberculosis, recurrent pneumonia and invasive cervical cancer [2] to the list of clinical conditions in the AIDS surveillance case definition published in 1987 [3] and expanded the AIDS surveillance case definition to include all HIV-infected persons with CD4+ T-lymphocyte counts of fewer than 200 cells/μL or ...

    en.wikipedia.org/wiki/WHO_Disease_Staging_System...

    WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease.

  7. HIV set point - Wikipedia

    en.wikipedia.org/wiki/HIV_set_point

    Long-term progressors (LTNPS) can remain stable in this stage for over a decade. An uninfected person has 500-1500 CD4 T cells/μL of blood. When this count lowers to less than 500 CD4 T cells/μL, opportunistic infections can occur where the immune system is no longer able to fight pathogens it would have easily cleared in an unimpaired state ...

  8. Helper/suppressor ratio - Wikipedia

    en.wikipedia.org/wiki/Helper/suppressor_ratio

    Normal values (95% confidence intervals) are approximately 30-60% CD4 and 10-30% CD8 depending on age (ratio 0.9 to 3.7 in adults). [1] One reason for abnormal results is the loss of CD4-positive cells to the human immunodeficiency virus (HIV) infection. The loss of CD4-positive cells to HIV infection can result in various distortions in the ...

    Stage 2: CD4 count 200 to 500 cells/μL and no AIDS-defining conditions; Stage 3: CD4 count ≤ 200 cells/μL or AIDS-defining conditions; Unknown: if insufficient information is available to make any of the above classifications. For surveillance purposes, the AIDS diagnosis still stands even if, after treatment, the CD4 + T cell count rises ...
