Typhoid fever , caused by a gram negative bacteria Salmonella typhi , remains a significant global health concern. Accurate and timely diagnosis of typhoid fever is crucial for appropriate patient management and effective control of the disease. Current methods of diagnosis include Serology based tests like the convenonal WIDAL test and Rapid Card Tests (Typhidot Or Enterocheck) and the Blood Culture test. In recent years, molecular testing techniques, particularly Reverse Transcription Polymerase Chain Reaction (RT-PCR), have emerged as a significant advancement in typhoid diagnosis. The Limitations of Traditional Methods: The Widal test , based on the detection of antibodies against S. Typhi and S. paratyphi antigens, has long been used for typhoid diagnosis. However, it has several limitations, including cross-reactivity, lack of specificity, unable to diagnose in early stage (first week) and the inability to differentiate between current and past infections.
