Monitoring CD4+ T Cells: Key Indicator of HIV Immune Status

CD4+ T-cell count is the primary marker for immune health in HIV infection.

Why It Matters

  • HIV targets and destroys CD4+ T cells, weakening immunity.
  • Declining counts increase risk of opportunistic infections.
  • Guides treatment decisions (e.g., when to start ART).
  • Tracks effectiveness of antiretroviral therapy.

Regular monitoring allows timely adjustments to care plans and helps maintain immune function.
