2. Viral load monitoring for HIV - Wikipedia

   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 ...

3. Diagnosis of HIV/AIDS - Wikipedia

   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.

4. CD4+/CD8+ ratio - Wikipedia

   en.wikipedia.org/wiki/CD4+/CD8+_ratio

   Patients with tuberculosis show a reduced CD4 + /CD8 + ratio. [9] HIV infection leads to low levels of CD4 + T cells (lowering the CD4 + /CD8 + ratio) through a number of mechanisms, including killing of infected CD4 +. Acquired immunodeficiency syndrome (AIDS) is (by one definition) a CD4 + T cell count below 200 cells per μL.

   CD4 counts should rise 50 to 100 cells per ml in the first year of therapy. [56] There can be substantial fluctuation in CD4 counts of up to 25% based on the time of day or concomitant infections. [95] In one long-term study, the majority of increase in CD4 cell counts was in the first two years after starting ART with little increase afterwards.

   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 ...

   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 ...
