Comparative study of NT antibody titers, IF antibody titers, and ELISA(IgG) antibody titers against HHV-6 and HHV-7. A histogram based on the titers of each antibody against these viruses were illustrated for 60 serum samples from the young group (subjects 2 to 18 years old [y.o.]) and 55 serum samples from the adult group (subjects 22 to 88 y.o.), respectively. A histogram based on ELISA(IgG) antibody titers was plotted by intervals of 0.2 optical density units. Secondary antibody used for IF antibody detection was directed against whole IgG (heavy plus light chain) of human immunoglobulins. Secondary antibody used for ELISA(IgG) antibody detection was directed against γ-chain specific IgG of human immunoglobulins.
