About microbiologyinfo.com
Widal Test is a renowned brand known for its agglutination test, detecting serum agglutinins (H and O) in patients with typhoid and paratyphoid fever. Developed by Georges Ferdinand Widal in 1896, this test is crucial in diagnosing typhoid fever in endemic areas lacking culturing facilities. By testing for O and H antibodies, Widal Test provides accurate results using Salmonella antigen suspensions in slide and tube techniques.
The test principle revolves around the reaction between patient antibodies and Salmonella antigens, causing visible clumping. With precise preparation of Widal antigens and detailed procedures for slide and tube tests, the brand ensures reliable results. The interpretation involves detecting agglutination as a positive result and determining serum titres for clinical significance.
Widal Test is a trusted choice for accurate diagnosis and monitoring of typhoid and paratyphoid fevers
