The Widal test is done by a General Physician to the mainstay of typhoid fever diagnosis for decades. It is used to measure agglutinating antibodies against H and O antigens of S typhi. Neither sensitive nor specific, the Widal test is no longer an acceptable clinical method.

A diagnosis of typhoid fever can usually be confirmed by a General Physician analyzing samples of blood, poo (stools) or pee (urine). These will be examined under a microscope for the Salmonella typhi bacteria that cause the condition.
