Typhoid is an enteric infection that is caused due to usage of dirty or contimnated water. A Typhidot Test is a screening test for typhoid fever performed using a blood sample. Typhoid fever, also called enteric fever, is a bacterial infection caused by Salmonella typhi. Typhoid fever is one of the most common bacterial infections in low-income nations, including India. The Typhidot Test evaluates the presence of immunoglobulin M (IgM) in the blood. It can thus indicate the presence or absence of the Salmonella species in the blood.
The Typhidot test is easy to perform and does not require any special equipment training for the staff. Besides, the results are also easy to interpret. Hence, the Typhidot Test can be useful as a complementary test to the Widal test and blood culture in diagnosing typhoid fever.

The Typhidot Test is a dot enzyme-linked immunosorbent assay (ELISA) that can detect antibodies IgG and IgM in the human body. The body produces these antibodies against the bacteria's outer membrane protein (OMP). The test becomes positive within two to three days of Salmonella infection. It indicates the presence of IgG and IgM in the blood.

The sensitivity and specificity of the Widal Test on blood cultures is 53% and 83%, respectively. In contrast, the Typhidot Test on blood cultures has a sensitivity and specificity of 93% and 83%, respectively. Hence, the Typhidot Test has higher sensitivity compared to the Widal Test.
