Correlation between Enzyme-Linked Immunosorbent Assay and Immunofluorescence Assay with Lytic Antigens for Detection of Antibodies to Human Herpesvirus 8

The purpose of this study was to evaluate, in Kaposi's sarcoma patients, the correlation between antibody titers to the lytic antigens of human herpesvirus 8, as assessed by immunofluorescence assay, and values obtained by an enzyme immunoassay. The methods showed a stringent correlation, r = 0.625 (P < 0.001).
