The relation between indirect ELISA (IE) and the hemagglutination (HI)
test was studied in 240 serum samples from laying hens submitted to d
ifferent systems of vaccination against Newcastle disease. A high corr
elation was obtained between the two serologic tests, although a wide
variation in the absorbance was observed when using IE for sera with t
he same HI liter.
