Johne's Testing Options

Milk test screen

An easy, non-invasive, cost effective way to annually screen the milking herd and monitor JD prevalence. 
 

Individual serum ELISA

The most economical individual test method for screening animals not in the milking herd. As animals in earlier stages of the disease may not be shedding and some animals are intermittent shedders making the antigen ELISA a better screening tool than PCR.
