  1. 1. The cutoff value of was 0.105, which was calculated from the twice that of mean OD of the negative control plus 0.005. The mean OD of the negative control is taken as least as 0.050
  2. 2. # indicate the sample was positive for KHB ELISA only (502019, 509344 and 573590)
  3. 3. & indicate the sample was positive for InTec ELISA only (506591)
