Bacterial meningitis is a serious disease with potentially lethal consequences. Rapid and accurate diagnosis and treatment are, therefore, critical. The bacterial antigen test (or BAT) was introduced in the 1980s as a rapid test for common bacterial causes of meningitis. It screens cerebrospinal fluid for antigens of the classic bacterial meningitis pathogens, Streptococcus pneumoniae, Haemophilus influenzae type b, Group B streptococcus, Neisseria meningitidis, and Escherichia coli K1.
