   Positive Equivocal Negative Total
IFAT Positive 68 3 4 75
  Equivocal 5 0 15 20
  Negative 34 15 3026 3075
  Total 107 18 3045 3170
  1. ELISA analytical sensitivity and specificity in comparison to IFAT are respectively 90.6% (68/75) (CI: 83.8 – 97.6%) and 98.7% (3056/3095) (CI: 98.3 – 99.1%), equivocal results considered as negative.
