The 5 tests in this panel
What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.
Widal, Salmonella Typhi O Titer
A Widal test titer for the typhoid bacterium's O antigen. One result cannot confirm or rule out typhoid fever.
Widal, Salmonella Typhi H Titer
A Widal test titer for the typhoid bacterium's H (flagellar) antigen. It can stay raised after an old infection or a vaccine.
Widal, Salmonella Paratyphi A (AH) Titer
A Widal test titer for the flagellar (H) antigen of Salmonella Paratyphi A, a relative of the typhoid bacterium.
Widal, Salmonella Paratyphi B (BH) Titer
A Widal test titer for the flagellar (H) antigen of Salmonella Paratyphi B, a relative of the typhoid bacterium.
Widal test (typhoid O and H agglutinins)
The overall reading of a Widal test, which looks for antibodies to typhoid bacteria. It is easy to misread and cannot confirm typhoid on its own.
