title: A method to rapidly convert Newcastle disease virus and infectious bronchitis virus ImmunoComb scores into conventional hemagglutination-inhibition titers.
abstract: ImmunoComb scores are highly correlated to hemagglutination-inhibition (HI) titers against infectious bronchitis virus and Newcastle disease virus. Statistical calculations permit using an individual COMBSCORE to predict the corresponding HI titer value. Tables are presented to facilitate the transformation of COMBSCORES into HI titers.
