The Widal test and Typhi Dot rapid test measure antibodies in the blood to detect infection with *Salmonella typhi*, the bacteria causing typhoid fever. The Widal test measures agglutinating antibodies against O and H antigens of *S. typhi*, indicating an active or recent infection. The Typhi Dot test detects IgM and IgG antibodies, providing a quicker diagnosis. Both tests help identify typhoid fever but vary in accuracy and are often used alongside clinical evaluation and other diagnostic methods.

The Widal test and Typhi Dot rapid test are diagnostic tools used to detect typhoid fever, caused by *Salmonella typhi*.

The Widal test measures agglutinating antibodies (O and H) against *S. typhi* in the patient's serum, indicating an active or recent infection. It requires interpreting rising antibody titers over time, making it more accurate when paired with clinical symptoms and history.

The Typhi Dot test is a rapid serological test that detects IgM and IgG antibodies against *S. typhi*. It provides quicker results compared to the Widal test and is useful for early diagnosis. However, both tests have limitations in sensitivity and specificity and should be used alongside other clinical and laboratory findings for accurate diagnosis.
