Antigens Used In Widal Test at Harry Picou blog

Antigens Used In Widal Test. The “o” antigen, a somatic antigen, and the “h” antigen, a flagellar antigen. Paratyphi b (bh) and somatic antigen of s.typhi (o) usually become detectable in blood, 6 days after the onset of infection. The main principle of widal test is that if homologous antibody is present in patients serum, it will react with respective antigen in the reagent and gives visible clumping on the test card. The widal test is a serological agglutination test used to diagnose enteric fever caused by salmonella typhi and salmonella paratyphi. During infection with typhoid or paratyphoid bacilli, antibodies against flagellar antigen of s. The widal test employs various antigens to assess the immune response comprehensively. Antigens specifically prepared from salmonella are used in the widal agglutination test to detect the presence of antibodies in patients’. It detects specific antibodies in the patient’s serum. The widal test works by checking these specific salmonella antibodies in the patient's serum using prepared salmonella antigens (commercially.
