A high immunity status is the best way to keep healthy poultry flocks. Using baselines for ELISA serology is a useful tool for monitoring this status.
Poultry health reality is variable in different poultry-producing areas of the world. However, the diagnostic tools veterinarians use to understand and measure different aspects of poultry health (serology, virology, bacteriology) are similar.
The use of ELISA technology is quite universal and there are ways to manipulate data to make it useful for day-to-day decision-making. The objective of this text is to describe a manner to analyze ELISA serology data and make it more useful to the poultry producer wherever ELISA serology is used.
Use of ELISA and definition of baseline
ELISA technology used in avian serology 
It is relatively easy and probably recommendable for high throughput laboratories to produce yearly baselines for their poultry industry user base. Short of that service, companies themselves should monitor their own baselines.
Sampling strategies
There are 3 main objectives for ELISA testing:
It is for the second objective, monitoring for response to vaccination, that baselines are most used, although they will
