Typhoid fever is diagnosed by testing for antibodies produced against the bacteria Salmonella typhi, which causes the condition. In most countries where the disease is widespread, treatment is started based on symptoms while these tests are processed by the laboratory to confirm the presence of disease.
An outline for the diagnosis of typhoid fever is given below:
The Widal test involves testing for agglutinating antibody levels against O antigens which usually appear 6 to 8 days after disease onset and H antigens which appear on days 10 to 12. However, the use of more recent tests such as the IDL Tubex test and the Typhidot test allow for a more rapid detection of the antibodies, leading to a faster diagnosis.
