Since 2014, AHL has been following the testing procedures recommended in research from Cathy Bauman et al. at the University of Guelph(1). This research indicated that the MAP Paracheck (Prionics) ELISA kit was the most sensitive test for antibody detection in goats. AHL has been sending submissions for this test to an equivalent (AAVLD accredited) laboratory. Currently, the Paracheck kit is unavailable in North America. AHL will now be sending caprine serologic samples to an equivalent lab (AAVLD accredited) that uses the Zoetis MAP antibody ELISA test kit. This test has been validated in cattle and goats.
