Cytomegalovirus (CMV) antigenemia was directly detected in
polymorphonuclear leukocytes (PMNLs) from transplant recipients by using
flow cytometry (FC). Two fixation and permeabilization methods and seven
anti-CMV monoclonal antibodies (MAbs) were evaluated. 1C3, SL20, and
NEA-9221 MAbs were more efficacious. The antigenemia detection threshold of
FC was 0.05% positive PMNLs, and percentages correlated well with DNA viral
load and the appearance of clinical symptoms.
