Indirect immunoperoxidase technique (IIP) has been employed for determination of IgG antibody titer to cytomegalovirus (CMV) in sera from 110 blood donors. Titers have been compared with complement fixation (CF) and indirect fluorescent antibody (IFA) technique titers, the latter being applied to determination of all specific antibody classes. Within the variability range of the quality of reagents employed in different tests, it seems reasonable to conclude that the IIP technique is as sensitive as IFA and much more sensitive than the CF test. Considering that the CF test is able to detect only IgG antibody, the advantage of using immunohistochemical techniques is obvious. Moreover IIP does not need the fluorescence microscope and reading the results is easier and can be delayed. Non specific staining of the Golgi area is shared by both techniques, but endpoint determination has to take into account only the nuclear virus specific labelling of the inclusions.
