The Widal test is a diagnostic tool used to detect antibodies against Salmonella typhi, the bacteria that causes typhoid fever.
The Widal test is based on the agglutination reaction, where antibodies in the patient's serum react with antigens from the Salmonella bacteria.
A positive Widal test indicates the presence of antibodies against Salmonella typhi, but it does not differentiate between acute and past infections.
The Widal test is often used as a screening test for typhoid fever in areas where the disease is endemic.
