What condition is suggested by the test results indicating low CD4 percentages?

Low CD4 percentages in test results are primarily indicative of immunosuppression, which is a hallmark of certain viral infections, particularly HIV (Human Immunodeficiency Virus). The CD4 T-cell count is a critical parameter in assessing the immune status of an individual, as these cells play a vital role in orchestrating the immune response against infections.

In the context of HIV, the virus specifically targets CD4 T-cells, leading to their depletion over time. A significant reduction in CD4 count signals an advanced stage of infection and an increased risk for opportunistic infections and other complications associated with the virus. Monitoring CD4 levels is essential for evaluating the progression of HIV and the effectiveness of antiretroviral therapy, as effective treatment can help restore CD4 counts and improve immune function.

While bacterial infections, autoimmune disorders, and fungal infections can also affect immune system function, they are not primarily characterized by a pronounced reduction in CD4 T-cell levels in the same way that HIV does. For example, bacterial infections may lead to an increase in certain immune cells as they trigger the immune response, rather than a decrease in CD4 cells specifically. Hence, when interpreting low CD4 percentages, viral infections like HIV are the primary condition that is suggested by
