First of all mentionIs it ELISA of ND or IB? also mention name of Kit used for ELISA?Then mention no of vaccine shots done from day one to 46 weeks of age, for which ELISA is required.After that CV%age zero for 18 samples doesn't look possible, as same value for 18 samples is not possible practically.

Very informative article. I would like to add some other causes of Gizzard erosions i.e. ND, Avian Influenza, Marek's Disease,Chicken Infectious Anemia and Megalobactor infection.
