  1. Indication
    1. Detecting HIV related Immune Deficiency
    2. Monitoring HIV Disease
    3. Used in combination with Plasma Viral Load Testing
  2. Efficacy
    1. Cell counts vary widely from lab to lab
      1. Use the same lab to follow patients
    2. Diurnal cell count variation (from 50-150 cells/mcl)
    3. May drop to 50% with acute comorbid illness
  3. Normal
    1. Non-HIV patients: 800-1200 cells/mcl
  4. Interpretation
    1. See HIV Course
    2. Each CD4 Count 10% rise decreases progression risk 15%
    3. Stage 1: CD4 500 Cells/mm3 or more
    4. Stage 2: CD4 200 to 499 Cells/mm3
    5. Stage 3: CD4 <200 Cells/mm3 or AIDS-Defining Illness
