Additional Instructions

The neonatal diarrhea study panel should be requested for young calves. The neonatal diarrhea study includes bovine diarrhea PCR, bacterial culture, and detection of E. coli virulence factors by PCR if the animal is less than two weeks of age.

Due to the likelihood of positive samples and lack of validation data, the laboratory will not pool samples.
