HUMORAL IMMUNITY
(A) Neutralize bacterial toxins
Evaluation of humoral immunity consists primarily of
(B) Activate the alternative pathway of complement
(C) Inhibit the growth of Mycobacterium tuberculosis
measuring the amount of each of the three important
(D) Inhibit the growth of virus-infected cells by enhancing the
immunoglobulins (i.e., IgG, IgM, and IgA) in the patient’s
production of perforins
serum. This is usually done by nephelometry. Immunoelec-
trophoresis can also provide valuable information. These
techniques are described in Chapter 64. ANSWERS
