Book a Test- Widal Test (Slide Agglutination)

The Widal test, also known as the slide agglutination test, is a diagnostic tool used to detect the presence of antibodies against Salmonella Typhi, the bacteria that causes typhoid fever. The test is based on the principle of agglutination, where antibodies in the patient's blood react with antigens from the bacteria, causing the formation of visible clumps. The Widal test is a simple and rapid diagnostic tool that can be used to support the diagnosis of typhoid fever. The test is typically performed on a blood sample, and the results are usually available within a few hours. A positive result indicates the presence of antibodies against Salmonella Typhi, which suggests that the patient has been infected with the bacteria. However, the test is not foolproof, and false-negative results can occur, especially in the early stages of the disease.
