T. Marrodan et al., Evaluation of three methods to measure anti-Brucella IgM antibodies and interference of IgA in the interpretation of mercaptan-based tests, J MED MICRO, 50(8), 2001, pp. 663-666
The results of a dipstick assay for the detection of immunoglobulin M (IgM)
to Brucella smooth lipopolysaccharide (S-LPS) correlated with those of an
enzyme-linked immunosorbent assay (ELISA) for IgM and of the serum agglutin
ation test (SAT) performed with and without dithiothreitol, Two sera which
were dithiothreitol-sensitive and were dipstick negative were shown to cont
ain specific IgA, The dipstick assay is recommended as a simple method for
detecting specific IgM antibodies in acute-phase brucellosis patients.
