Question

What is the WBC Count (Total WBC, ANC, CD4) if all of them go below their thresholds?

Answer 1

If white blood cell counts (total WBC count, ANC, CD4) go below their thresholds, it suggests a compromised immune system, such as in AIDS. A CD4+ T cell count below 400 indicates an impaired immune response.

Step-by-step explanation:

In a healthy person, the total white blood cell (WBC) count ranges from 1,000 to 11,000 per microliter of blood. However, if all three types of white blood cells (total WBC count, absolute neutrophil count, and CD4+ T cell count) go below their respective thresholds, it can indicate a compromised immune system. For example, a CD4+ T cell count dropping below 400 per microliter suggests an impaired immune response. Additionally, a CD4+ T cell count falling below 200 cells per microliter is a criterion for diagnosing acquired immunodeficiency syndrome (AIDS).
