What is the range for normal adult CD4+ cell counts?

• A. 200 - 400 cells/mm
• B. 300 - 600 cells/mm
• C. 500 - 1500 cells/mm
• D. 600 - 800 cells/mm

Answer: (C)

The range for normal adult CD4+ cell counts is 500 - 1500 cells/mm. This range is important because CD4+ T cells play a crucial role in the immune system, particularly in helping the body fight off infections. A normal count indicates a well-functioning immune system, while lower counts can suggest a compromised immune response, such as found in individuals with HIV/AIDS. The selected range encompasses the typical baseline levels found in healthy adults. Levels below this normal range can indicate potential health issues, necessitating further investigation or monitoring. Regular monitoring of CD4+ counts in at-risk populations is vital for assessing immune health and guiding treatment decisions in clinical settings.
