What is a WIDAL - SLIDE AGGLUTINATION TEST?

The Widal Slide Agglutination Test is a rapid diagnostic test used to detect antibodies against Salmonella typhi and Salmonella paratyphi, the bacteria responsible for typhoid and paratyphoid fever. In this method, patient serum is mixed with specific antigens on a slide, and visible clumping (agglutination) indicates the presence of antibodies. The purpose of this test is to provide a quick screening tool for suspected typhoid infections, helping clinicians confirm diagnosis and initiate timely treatment to prevent complications.
