Outside: Call to inquire
Agglutination Test and additional testing (see comments)This test kit is used for the presumptive diagnosis of Brucella canis in dogs by detecting specific antibodies that are formed 1 to 4 weeks after infection. Definitive diagnosis of Brucella canis infection is based upon culture and isolation of B. canis from the animal. This screening test includes a B. canis rapid slide agglutination test (RSAT) and B. canis 2-Mercaptoethanol rapid slide agglutination test (2ME –RSAT). False positive results that may occur due to potential nonspecifc agglutination is ruled out by performing 2ME-RSAT following manufacture's recommendations. This test detects exposure to only B. canis not to other Brucella spp. such as B. suis or B. abortus.

This screen includes additional testing at NVSL for a buffered acidified plate agglutination (BAPA). If positive they will also run a fluorescent Polarization Assay (FPA) for an additional charge.
