What is a Widal Test?
The Widal Test (Slide Agglutination method) is a serological blood test used to detect antibodies against Salmonella bacteria. It identifies O (somatic) and H (flagellar) antigens in the blood, which helps in supporting the diagnosis of typhoid or paratyphoid fever.
This test is widely used in clinical settings, especially in regions where typhoid fever is common. However, it is usually interpreted along with clinical symptoms and may sometimes be confirmed with more specific tests like blood culture.

Doctors recommend this test to:
- Detect typhoid fever
- Evaluate prolonged fever
- Screen for Salmonella infection
- Support clinical diagnosis of enteric fever
- Investigate abdominal pain and weakness
- Monitor infection trends in endemic areas
- Assist in early treatment decisions
- Differentiate febrile illnesses

| S. Typhi H | < 1:80 |
| S. Paratyphi A | < 1:80 |
| S. Paratyphi B | < 1:80 |

Understanding High and Low Widal Test Results
High Widal Titer
Elevated antibody levels may suggest:
- Typhoid fever
- Recent Salmonella infection
- Cross-reactivity from other infections
- Previous exposure or vaccination (in some cases)
Low or Normal Results
