Lawsonia intracellularis in horses can be detected by serologic or molecular detection methods. These tests can be run separately or together.


The ELISA for Lawsonia intracelluris is a 2nd generation assay in an ELISA format. It detects serum antibodies against L. intracelluris which with concurrent hypoalbuminemia or hypoproteinemia supports a diagnosis of equine proliferative enteropathy (EPE). A serum albumin test is also available from EDS.


The real-time PCR for Lawsonia intracellularis is performed on feces.
