NABP Exam NAPLEX Topic 8 Question 71 Discussion

A CD4 count of 180 cells per cubic meter is considered very low -- typically an indicator that the patient has an immunocompromised state, such as AIDS. CD4 counts are a measure of healthy T-cell levels. The lower the count, the more susceptible the patient is to opportunistic infections. A normal range is between 500 and 1,500 cells.
