*5.2.2 Serum agglutination test (SAT)*

Although this test was first introduced in 1897, it still relies upon today for the serodiagnosis of brucellosis. In endemic areas, SAT is the most widely employed serological test. In non-endemic locations, an agglutination titer of 1:160 or higher is regarded as noteworthy, but in endemic areas, a titer of 1:320 or higher is required.
