Highlights
The Widal test is a diagnostic procedure that detects the presence of specific antibodies in the blood, indicating an infection caused by Salmonella Typhi or Salmonella Paratyphi. A notable increase in antibody titers over time, or a high initial titer, typically points to an active infection. This test is especially valuable in areas with limited access to advanced diagnostic facilities, providing a simple and accessible method for identifying enteric fever and aiding in timely treatment decisions.
