Reference Range: Less than 1:20 = Negative 1:20-1:80 = Equivocal Greater than or equal to 1:160 = Positive A presumptive diagnosis of tularemia can be made based on a four-fold rise in titer between acute and convalescent titer or an acute titer of 1:160 or greater in the presence of compatible symptoms. Equivocal titer may be due to crossreactive antibodies (Brucella, Yersinia or Proteus OX19)
