Immune adherence hemagglutination: further observations on demonstration of antibody to varicella-zoster virus.

The immune adherence hemagglutination test for measurement of antibody to varicella-zoster (V-Z) virus is well suited to performance in a routine serology laboratory. This test is useful in assessing susceptibility to varicella, measuring antibody to V-Z virus in globulin preparations, and evaluating some effects of passive immunization. Since the complement-fixation test for antibody to V-Z virus lacks sensitivity and the fluorescent antibody to membrane antigen test is not readily available, the immune adherence hemagglutination test may be of practical value in patient management.
