Widal test is a blood test that helps in diagnosing enteric fever (typhoid fever and paratyphoid fever), which is caused by consuming contaminated food and drinks. The serum agglutination test is a part of the widal test. People with typhoid fever have homologous antibodies present in their blood. The widal test is performed by using either the slide method or the test tube method.

A widal test is done if you develop the following symptoms:
The widal test is used for detecting antibodies in the blood against two antigens (O & H) of Salmonella enterica, the typhoid-causing bacteria. Agglutination refers to the clumping of particles that happens when an antigen gets mixed with its antibody. When this test is done using a slide, it is called slide agglutination. Similarly, when it is done using a test tube, it is called tube agglutination. Generally, tube agglutination is used more frequently than slide agglutination in the widal test. Apart from Salmonella Typhi antigens “H” and “O”, S. Paratyphi antigen “H” is used in this test.
One week after developing the typhoid fever, the antibodies against Salmonella antigens “O” and “H” usually appear in the serum. Another widal test can be done 7-10 days after the first one to examine the levels of antibodies.
No side effects are associated with a widal test, although, for a few days, some pain might be felt in the area from where the blood is taken using a needle.
