Use of onsite typhoid IgG/IgM combo test as rapid diagnostic test for typhoid fever

Abstract: Background The incidence of typhoid fever is increasing in Egypt. The Widal test is the evaluation most widely used in Egypt for diagnosis, but it has many drawbacks; therefore, new diagnostic tools are needed. Our aim was to evaluate the diagnostic accuracy of the onsite typhoid IgG/IgM combo rapid test in diagnosing typhoid fever. Method Blood specimens were collected from 90 patients (of all ages) who presented with fever of more than 4 days’ du… Show more

“…On the other hand, more than 50% of resistant cases were found in treatment by nalidixic acid (76%), ampicillin (98%) and amoxicillin (98%). These findings were similar to the findings of another study conducted by Mohamed et al ( 2023) [16]. Another study by Bulbul Hasan et al [10] found an antimicrobial susceptibility pattern of 16 isolates of S. typhi showing that no isolate was resistant to Ceftriaxone and Ceftazidime, only 03(18.75%) was resistant to Ciprofloxacin and Azithromycin whereas 10(62.5%) were MDR showing resistance to Ampicillin, Cotrimoxazole and Chloramphenicol which are first-line anti typhoidal drugs.…”

“…The Typhoid IgG/IgM combo test (lateral flow immunoassay) results were positive in approximately 24% of all patients and demonstrated 72.4% sensitivity, 98.4% specificity, 95.5% positive predictive value and 88.2% negative predictive value. 5 Our patient started with a fever but without respiratory symptoms. As a patient with a pacemaker implant, he was thoroughly investigated for an infection.…”
