In an HIV patient responding well to antiretroviral therapy, virological suppression is indicated by which combination of values?

  1. CD4 >500 cells/µL AND viral load <1,500 copies/mL
  2. CD4 >200 cells/µL AND viral load <10,000 copies/mL
  3. CD4 >350 cells/µL AND viral load <5,000 copies/mL
  4. CD4 >100 cells/µL AND viral load undetectable
Show answer and explanation

Correct answer: A. CD4 >500 cells/µL AND viral load <1,500 copies/mL

  • A. CORRECT. Per the recall source, virological suppression is indicated by CD4 count >500 cells/µL AND viral load <1,500 copies/mL. This combination suggests effective antiretroviral therapy with adequate immune reconstitution. Additionally, low viral load (<75 copies/mL on sensitive assays) is the clinical undetectable threshold.
  • B. Incorrect. CD4 >200 + VL <10,000 describes a patient stabilized but not optimally suppressed.
  • C. Incorrect. These values describe partial therapeutic response but not optimal suppression as described in the recall.
  • D. Incorrect. This combination does not reflect the specific threshold given in the recall context.
