background and objective: the diagnosis of typhoid fever in children is a challenge due to the non-specific clinical picture. the current role of the widal test for diagnosis in developing countries has not been clear. materials and methods: charts were reviewed on all children ≤ 15 years of age discharged from 5 pediatric teaching hospitals in tehran from 1991 to 2004 with a diagnosis of typho...

BACKGROUND The Widal test is the most common, specific and quick diagnostic method available in the world for diagnosis of typhoid fever; however, false negativity is one of the obstructive features of the test. The aim of this study was to evaluate the associated factors with Widal test negativity in an endemic area. METHODS Widal test negativity was retrospectively analyzed among culture-pr...

typhoid fever is endemic in iran. isolation of s. typhi is a gold standard for diagnosis. laboratory diagnosis of s. typhi infection relies on serological tests such as the widal test. this study describes seroprevalence of to and th antibody in nonfebrile healthy and febrile with non-typhoid illness. for detection of sensitivity and specificity of widal test in typhoidal fever diagnosing widal...

Introduction: Enteric fever continues to be a global health problem and isolation of organism from blood is the gold standard for the diagnosis. Objectives: Aim of this study was to find out the usefulness of three different methods such as blood culture, clot culture & Widal test for diagnosis of enteric fever. Materials & Methods: Total number of blood samples collected was 290 from patients ...

INTRODUCTION Although typhoid fever is confirmed by culture of Salmonella Typhi, Widal test is widely used in India but little information exists about its reliability. MATERIALS AND METHODS We examined the performance of Widal test in our hospital for diagnosis of typhoid fever in children. Hundred consecutive pediatric in-patients for whom, the Widal test was requested were grouped into fou...

BACKGROUND AND PURPOSE Widal test is frequently applied for the detection of Salmonella agglutinins to diagnose Salmonella enterica serotype Typhi infection. There are however a number of controversies challenging the diagnostic utility of this test. This study was performed to determine the prevalence of Salmonella agglutinins in patients with other febrile illnesses and healthy blood donors. ...

Isolation of the causative organism from the blood and other body fluids remains the definitive test for the diagnosis of typhoid fever. But this isolation requires ...

Introduction: Typhoid fever the common cause of morbidity and mortality especially in the developing countries where Widal test is routinely used as diagnostic tool to rule out the disease. The diagnostic ability of Widal test is debatable as the test method has a low sensitivity, specificity and positive predictive value (PPV). Therefore, reviewing articles across the world regarding the diagn...

BACKGROUND Widal test, which has poor predictive outcomes in predominant typhoid population, is not standard enough to predict accurate diagnosis. This study aims to compare the diagnostic accuracy of Widal test to ELISA using blood culture as gold standard. METHODS The blood samples were collected in Capital Hospital, Kathmandu, Nepal from febrile patients having ≥48 h fever in 3 years study...
