Western Blot Activity

Question 4

Which patient(s) is/are HIV positive by Western blot?
Patients B and C are both positive
Incorrect. Although patient B may have antibodies directed against p24, p66 and p55, the serum contains no antibodies against HIV envelope glycoproteins, gp160, 120. Therefore this test is indeterminate for patient B. Patient C is HIV positive because the serum shows reactivity to gp160, 120, p24, 66 and 55.
