The Widal Test (Qualitative) at Pamel Laboratories is a rapid serological test used to detect the presence of antibodies (agglutinins) against Salmonella typhi and Salmonella paratyphi in the blood. It is commonly used as a screening test for typhoid fever, particularly in patients with prolonged fever, abdominal pain, weakness, and headaches.
This qualitative version indicates whether the relevant antibodies are present or absent, making it useful for initial diagnosis or exclusion of enteric fever.
What the Test Detects:
-
O antibodies (against somatic antigen of S. typhi)
-
H antibodies (against flagellar antigen of S. typhi)
-
May also detect antibodies to S. paratyphi A & B
Purpose of the Test:
-
Screen for typhoid and paratyphoid fever
-
Evaluate patients with fever of unknown origin
-
Support clinical diagnosis in endemic regions
-
Provide basis for further quantitative testing or culture confirmation
