Question 4

Which patient appears to be the one that is HIV infected?

From the flow diagrams, both patients have low CD4 counts and therefore appear to be HIV infected.

INCORRECT
One patient has a depressed CD4+ T cell count while the other patient does not. Although several different conditions can cause a depression in CD4+ cells, you were told that one patient was HIV+ and the other was not.
