Question

Quizplus · Accepted Answer

The number of CD4 T cells is used to monitor the progression of HIV infection and determine the stage of the disease. As HIV infects and destroys CD4 T cells, the number of these cells decreases and serves as a marker for the progression of the disease. The stage of HIV infection is determined by the CD4 T cell count and the presence of opportunistic infections. The other options - the number of CD8 T cells, the number of HIV RNA copies, and the HIV antibody titer - may also be important in monitoring HIV infection, but they are not used to determine the stage of the disease.
